The Large Hadron Collider (LHC) is studying the structure of matter at sub-nucleon distance scales by colliding protons together at high center of mass energy. The LHC has a broad scientific program, performing studies of QCD, heavy quarks, the W and Z electroweak gauge bosons, the top quark, and the recently discovered Higgs boson. The LHC experiment also has a dedicated effort to search for evidence of new laws of physics, in the form of new particles or anomalies. The discovery of the Higgs boson and the null-findings of direct searches for new particles conducted during the 8 TeV run of the LHC places acute attention on the hierarchy problem and on the origin of masses for the quarks, leptons and electroweak gauge bosons.
The HEP effort at Los Alamos in LHC physics is focused on a number of related questions.
- How can the discovery potential of new physics searches at the LHC be improved?
- Where should we be looking for new physics where we currently are not?
- What new physics can contribute to the decay of the Higgs boson?
- Can interactions between dark matter and neutrinos be important?
- What are the implications of direct searches for new physics at the LHC on indirect
- searches for new physics in low-energy experiments?
