Oral Presentation Beyond Standard Model Physics Beyond Standard Model


Mr nathan sherrill (Indiana University)


An approach is presented for the calculation of high-energy hadron-lepton and hadron-hadron interactions at large momentum transfer in the presence of Lorentz-violating background fields affecting quarks. Cross sections for deep inelastic scattering and the Drell-Yan process are calculated at leading order for minimal and nonminimal Lorentz violation using the Standard-Model Extension, an effective field theory characterizing general Lorentz-violating effects for the Standard Model fields and General Relativity. Estimated bounds are placed using sidereal-time analyses of existing HERA, LHC, and future US-based electron-ion collider data.
