ALICE event display of a Pb-Pb collision at 2.76A TeV. One of the first lead-lead collisions at the Large Hadron Collider, recorded by the ALICE detector in November 2010. In this collision of lead nuclei at a small impact parameter (central collision), 1209 positively-charged (darker tracks) and 1197 negatively-charged (lighter tracks) particles are produced, about 80 percent are pions. The curvature of a track in the magnetic field of ALICE (0.5 T) is inversely proportional to the momentum of the particle. The cylinder is the Time Projection Chamber of ALICE, with a diameter of 5 m and a length of 5 m, recording the charged particles in three dimensions with the equivalent of 500 million pixels.

Physics 366. Elementary Particles with Prof. Andrew Larkoski.

September 13, 2018

Introduction to the theory and phenomenology of elementary particle physics.  The goal of this course is to get students to be able to understand and interpret data from modern particle physics experiments with a focus on the Large Hadron Collider.  Key ideas in particle physics are developed with guidance from physical intuition, such as symmetries and conservation laws, particle spin, Bjorken scaling and evidence for constituents of protons, scale invariance and jets in the strong force, parity and charge conjugation violation of the weak force, and neutrino oscillations.  Extensive examples from published data are used to test the physical theories explored in this class.  Prerequisite: Physics 201 and 202 and Mathematics 201 and 202. Lecture.

Prof. Larkoski is a theoretical particle physicist whose research focuses on the physics of the Large Hadron Collider experiment, located in Geneva, Switzerland. He is most interested in jets: collimated streams of particles that are the manifestation of the strong nuclear force, quantum chromodynamics, at exceptionally high energies. He was instrumental in that are now widely used in analyzing the data from the Large Hadron Collider. Prof. Larkoski earned his Ph.D. from Stanford and won the Wu-Ki Tung Award for outstanding contributions by an early-career researcher for his work on quantum chromodynamics.
