The astro-particle physics research group is currently involved in several projects: Dark Matter in Non-Standard Cosmologies: Standard Big Bang Cosmology provides a concrete method for theoretically determining the abundance of neutralinos (dark matter) at the present epoch. There is a natural connection between particle physics and representation theory, as first noted in the 1930s by Eugene Wigner. Its programme includes working at the energy and precision frontiers of physics and in studying the properties of quarks and neutrinos. Once we noted it, then it is pure math to show that the simple objects in our theory should be classified according to representations of the symmetry group of the lagrangian and the vacuum state. Return to faculty and school overview. Without the Higgs boson, the Standard Model would fail. . Humorously called the "God particle" in 1993 in a book of the same name by authors Leon Lederman and Dick Teresi, the Higgs boson plays a crucial role in the Standard Model of physics: it provides . The group is interested in a range of theoretical problems with a phenomenological emphasis (that is, with relevance to current or future experiments).

Particle Physics Theory Our group works on diverse topics in theoretical high energy physics, including physics beyond the Standard Model, field theory, quantum chromodynamics, conformal bootstrap, and early universe physics. As the recent discovery of the Higgs Boson, as well as direct evidence of cosmic inflation, have shown, there is great excitement and anticipation about the next round of compelling questions about the origin of particle masses, the nature of dark matter, and the role leptons, and in particular neutrinos, may . 54) (1982) 1. Group Theory in Particle Physics Joshua Albert November 19, 2007 1 Group Theory Group theory is a branch of mathematics which developed slowly over the years. A magnetic monopole is a hypothetical particle with a magnetic charge, a property analogous to an electric charge. For his contributions to neutrino physics. Let G be a finite group and H be a subgroup and let : H U ( W) be a unitary representation on a finite-dimensional hermitian vector space W.

Particle Physics was funded by the HEPP (High Energy Particle Physics) programme of the Research Council of Norway until 2020. Three of the fundamental forces result from the exchange of force-carrier particles, which belong to a broader group called "bosons". The study of Higgs Bosons and search for physics beyond the Standard Model at ATLAS, CERN, Geneva, Switzerland. To achieve this, the authors first give a brief introduction to the structure of Lie groups and algebras.

The Fermilab (1967) particle physics experiment describes an acellerated proton beam collision with a beryllium target that forms subatomic particles which propagate through the steel structure of the bubble chamber producing spiral shape liquid hydrogen bubble tracks that are used to determine the mass and energy of the subatomic particles. The Institute of Particle Physics promotes Canadian excellence in particle physics research and advanced education. RHIC Computing Facility . The particle theory group is activein a wide range of topics, including astrophysics, cosmology, the Standard Model, supersymmetry and string theory. Finding its origins in algebraic equations, number theory, and geometry, this eld would eventually be applied extensively to physics in the 20th century.

Phys. Broadly defined, particle physics aims to answer the fundamental questions of the nature of mass, energy, and matter, and their relations to the cosmological history of the Universe. Welcome from Group Leader, Professor Joost Vossebeld. The program is designed to simulate the physics processes that can occur in collisions between high-energy particles, e.g. It is critical for the relic abundance of neutralinos to match the . Thus U (1) = e ia = e ia(1) = e ia I is called an Abelian group in which different transformations commute. Our group is currently involved in experimental research involving the Belle and Belle II and ATLAS projects, as well as in theoretical particle physics research. Let us start with finite groups. The Nuclear and Particle Physics and Applications (P-3) group in the Physics division is looking for one or more postdoctoral researchers to work in the Low Energy Nuclear Physics Team on direct and indirect measurements of neutron induced reactions.
