high energy theoretical physics

The high energy theory group at Penn studies the fundamental forces of nature, early universe cosmology and mathematical physics. Although the word particle can refer to various types of very small objects (e.g. In May 2014, the Particle Physics Project Prioritization Panel released its report on particle physics funding priorities for the United States over the next decade. High energy physics is concerned with the most elementary building blocks of nature and the fundamental forces between them. A major effort at Ohio State is trying to discover the new physics beyond the Standard Model. String theory has a rich mathematical structure that is still being explored. Fax: 805-893-3307 The development of superconductors has been pushed forward by their use in particle physics. My group works at the interface of theoretical condensed matter, high energy, mathematical and atomic physics. Some theorists working in this area use the tools of perturbative quantum field theory and effective field theory, referring to themselves as phenomenologists. [1][2], Modern particle physics research is focused on subatomic particles, including atomic constituents, such as electrons, protons, and neutrons (protons and neutrons are composite particles called baryons, made of quarks), that are produced by radioactive and scattering processes; such particles are photons, neutrinos, and muons, as well as a wide range of exotic particles.

The major research areas of the theory group include lattice gauge theory (mostly about strongly coupled systems potentially appropriate to dark matter or to beyond-standard model phenomenology) and string theory and quantum gravity (mostly about the AdS/CFT correspondence). This work probes the limits of the Standard Model and therefore expands scientific understanding of nature's building blocks. There are several powerful experimental reasons to expect new physics, including dark matter and neutrino mass.

Can extra dimensions explain the cosmological constant or "dark energy"? Can we evaluate the QCD path integral numerically and obtain the masses of strongly interacting particles, their decay properties, and the properties of matter at high temperature? All members of this group are very active in constraining and exploringtheories beyond the Standard Model via both precision studies of Standard Model interactions and theinterpretationofdeviations from Standard Model expectations in a very broad spectrum of phenomena, from collider physics to astrophysicaland cosmological data.. Broida Hall NA61/SHINE is a large-acceptance detector located atCERN. One important non-collider effort is the determination of the neutrino masses, since these masses may arise from neutrinos mixing with very heavy particles. There has been rapid progress in this area in recent years, in part due to work of Princeton faculty and students, and it continues to be a fertile source of research problems. New crime scene investigation technique offers a hard look at the traces that particles leave before fleeing the scene.

Much of the effort to find this new physics are focused on new collider experiments. High Energy Physics (HEP)explores what the world is made of and how it works at the smallest and largest scales, seeking new discoveries from the tiniest particles to the outer reaches of space. Researchers demonstrated record accelerating cavity performance using a technique that could lead to significant cost savings. In more technical terms, they are described by quantum state vectors in a Hilbert space, which is also treated in quantum field theory. University. [6], The idea that all matter is fundamentally composed of elementary particles dates from at least the 6th century BC. Campus Map (Broida Hall), Main office hours [PST] [4] It was referred to informally as the "particle zoo". Any final theory of physics must incorporate a quantum theory of gravitation. The scope of their research include searches for new physics from many complementary areas, from new signatures in collider events to anomalies in flavor physics observables, all the way to astronomical and cosmological observations. The world's major particle physics laboratories are: Many other particle accelerators also exist. The theory group of Argonnes High Energy Physics Division performs high-precision calculations of Standard Model processes, interprets experimental data in terms of physics both within and beyond the Standard Model, and makes predictions for new, well-motivated experimental searches that attempt to provide answers to open questions. Zoom Virtual Office Hours, University of Colorado Boulder Regents of the University of Colorado Throughout the 1950s and 1960s, a bewildering variety of particles were found in collisions of particles from beams of increasingly high energy. High Energy Physics Particle accelerators are used to produce medical isotopes for research and treatment (for example, isotopes used in PET imaging), or used directly in external beam radiotherapy. Can we use quantum chaos theory to understand the emergence of thermal behavior in isolated systems, and also the quantum properties of black holes? There are many reasons to believe that the Standard Model is incomplete, and that there are other elementary particles and fundamental forces in nature. The activity in string theory and quantum gravity is aimed at developing a quantum theory that incorporates the physics of gravity and is valid down to the smallest length scales, where conventional quantum field theory can no longer be applied. Successful models of the fraught dynamics of two particle beams in close contact lead to smoother sailing in an area of particle acceleration. Important discoveries such as the CP violation by James Cronin and Val Fitch brought new questions to matter-antimatter imbalance. Can black holes be produced at particle accelerators? Tel: 805-893-3888 It includes the electroweak theory, which unites the weak and electromagnetic interactions and has a symmetry that relates the massless photon and the massive W and Z bosons. Email:physics@colorado.edu String theorists attempt to construct a unified description of quantum mechanics and general relativity by building a theory based on small strings, and branes rather than particles. Theoretical, computational, and interdisciplinary physics provide the vision and the framework for extending our knowledge of particles and the universe. The faculty in the group at present are Vijay Balasubramanian, Mirjam Cvetic, Justin Khoury, Burt Ovrut and Mark Trodden.

[citation needed] It may involve work on supersymmetry, alternatives to the Higgs mechanism, extra spatial dimensions (such as the RandallSundrum models), Preon theory, combinations of these, or other ideas. We can also investigate the existing array of particles in more depth at lower energies in search of clues to what lies beyond the Standard Model. What is string/M-theory - what is the underlying principle and the precise and complete formulation? TheCMS experimentis located inside the Large Hadron Collider (LHC) atCERNin Geneva, Switzerland. One important branch attempts to better understand the Standard Model and its tests. This application of string theory has already provided new insights into strongly coupled gauge theories, and it continues to be an exciting area. Might there be superstrings of cosmic size in the universe today? The prototype of such system is Quantum Chromodynamics, the theory of quarks and gluons which describes the strong nuclear force. [10][11], The current state of the classification of all elementary particles is explained by the Standard Model, which gained widespread acceptance in the mid-1970s after experimental confirmation of the existence of quarks. Black hole theory provides an important testing ground for the quantum theory of gravity and in recent work significant progress has been achieved in explaining black hole entropy and Hawking radiation from a more fundamental point of view. How did become the way it is today? 390 UCB Directions and Parking SC-25/Germantown Building My research interests are in physics beyond the standard model, particularly its signatures in collider and dark matter experiments, and more generally in the physics of strongly-coupled elementary particles, which I study numerically using large-scale computing. Inside Physics , Kavli Institute for Theoretical Physics (KITP). Santa Barbara,CA 93106-9530, We invite you to be part of the Departments success in educating the next generation of leaders. My particular interests include composite Higgs and composite dark-matter models, precision calculations of heavy-quark properties (which are an important input to experimental searches for new physics), and the dynamics of many-fermion gauge theories. Among the objectives of the group in Minnesota is to push our understanding beyond the Standard Model of electroweak interactions. UC Santa Barbara, Santa Barbara, CA 93106. TheCU CMS grouphas four current faculty members:John Cumalat,Kevin Stenson, Keith UlmerandSteve Wagneras well as an emeritus faculty member:Bill Ford. In the 20th century, physicists learned that all matter is composed of a relatively small number of elementary particles called quarks and leptons. In this video, DESI project participants share their insight and excitement about the project and its potential for new and unexpected discoveries. The Argonne Theory Group is active in exploring the particle physics Standard Model and in searching for avenues to go beyond it.

Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences, Journal of Cosmology and Astroparticle Physics, Qualifications Ground-breaking image reconstruction and analysis algorithms filter out cosmic rays to pinpoint elusive neutrinos. How can we use string theory to solve QCD and other quantum field theories? Researchers at the Intensity Frontier investigate some of the rarest particle interactions in nature and subtle effects that require large data sets to observe and measure. questions, How the Additional applications are found in medicine, national security, industry, computing, science, and workforce development, illustrating a long and growing list of beneficial practical applications with contributions from particle physics.[28]. The Dark Energy Survey has delivered dark energy constraints combining information from four of its primary cosmological probes for the first time. In addition, there are important non-collider experiments that also attempt to find and understand physics beyond the Standard Model. The members of the High Energy Theory Group have broad interests in string theory, quantum field theory, and the connections between the two. In addition, cosmological observations provide many useful constraints on the dark matter, although it may be impossible to determine the exact nature of the dark matter without the colliders. Another effort uses string theory to construct extensions of the Standard Model that go beyond quantum field theory. Colorado hosts a T2K computing center. The CU group (led by Professors Eric Zimmerman and Alysia Marino)is primarily focused on making in-situ and ex-situ measurements of the hadrons in the neutrino beam, to improve predictions for the neutrino flux. However, most particle physicists believe that it is an incomplete description of nature and that a more fundamental theory awaits discovery (See Theory of Everything). Febres Cordero and Reina focus on improving the theoretical accuracy of precision Standard Modelcalculations which are then compared with data taken at colliderexperiments such as the LHC. The known quarks, leptons, and gauge bosons and the electroweak and strong forces are all described by a relativistic quantum field theory known as the Standard Model.
