Experimental Program

 The main focus of our experimental research is at the Large Hadron Collider (LHC) at the European Laboratory for Particle Physics (CERN), near Geneva, Switzerland.

The LHC is the world's highest energy collider and it is probing physics and processes in a completely new energy regime. Early research focusses on the search for the Higgs  boson and the search for evidence of new types of particle production. The machine ran at 7 TeV center-of-mass energy in 2010 and 2011 and at 8 TeV in 2012. SInce 2015 it has been runing at 13 TeV. During 2013 and 2014 the machine will be upgraded to allow it to run at the higher energy of 13 TeV.

The UCR experimental group, consisting of Professors Clare, Ellison, Gary, Hanson, Long and Wimpenny are members of the Compact Muon Solenoid Collaboration (CMS), which is one of the two large multi-purpose experiments at the LHC. The UCR group currently has 4 postdoctoral researchers and 10 graduate students working on CMS.

On campus our facilities include a clean room used for silicon module testing and a mid-sized Tier 3 computing cluster (320 CPUs and 170 TBytes of disk storage) connected to the Open Science Grid (OSG). The OSG is the backbone of LHC computing in the US and is a part of the Worldwide LHC Computing Grid (WLCG).


Our data analysis interests include Higgs physics, searches for Supersymmetry, searches for heavy neutrinos and other new phenomena, and precision Top Quark measurements. On the hardware side, we are working on the CMS central silicon tracker, the hadron calorimeter and the endcap muon spectrometers.

Professor Gary is also active in Quantum Chromodynamics (QCD) research and is a member of the CTEQ Collaboration.

Professor Hanson is a member of the Neutrino Factory and Muon Collider Collaboration, which is carrying out a program of research and development towards a future muon-antimuon collider or a muon storage ring to produce an intense neutrino beam from the decays of the muons.
