Probing Lorentz invariance via diphoton decays of the Higgs boson
Alan Kostelecky, Connor A. Petway, Nathaniel Sherrill
The prospects for observing small departures from Lorentz invariance are studied using effective interactions of the Higgs boson with photons. A single operator of mass-dimension f…
Limits on New Lorentz-violating Bosons
P. Carenza, J. Jaeckel, G. Lucente +3
We obtain novel constraints on new scalar fields interacting with Standard Model fermions through Lorentz-violating couplings, bridging searches for scalar particles and Lorentz-sy…
Flavor-changing Lorentz and CPT violation in muonic atoms
Alan Kostelecky, W. P. McNulty, E. Passemar +1
Flavor-changing signatures of Lorentz and CPT violation involving muon-electron conversions in muonic atoms are studied using effective field theory. Constraints on coefficients fo…
Signals of nonrenormalizable Lorentz and CPT violation at the LHC
Enrico Lunghi, Nathaniel Sherrill
We examine nonrenormalizable Lorentz- and CPT-violating effective operators applied to the quark sector of the Standard Model. Using Drell-Yan events collected by the ATLAS and CMS…
Probing CPT invariance with top quarks at the LHC
A. Belyaev, L. Cerrito, E. Lunghi +2
The first model-independent sensitivity to CPT violation in the top-quark sector is extracted from ATLAS and CMS measurements of the top and antitop kinematical mass difference. We…
Electromagnetic Flavor-Changing Lepton Decays from Lorentz and CPT Violation
Alan Kostelecky, E. Passemar, N. Sherrill
Lorentz- and CPT-violating effects initiating two-body electromagnetic flavor-changing decays of charged leptons are studied in the framework of Lorentz-violating effective field t…
Snowmass 2021 White Paper: Electron Ion Collider for High Energy Physics
R. Abdul Khalek, U. D'Alesio, M. Arratia +105
Electron Ion Collider (EIC) is a particle accelerator facility planned for construction at Brookhaven National Laboratory on Long Island, New York by the United States Department o…
Quark-sector Lorentz violation in -boson production
Enrico Lunghi, Nathan Sherrill, Adam Szczepaniak +1
Quark-sector Lorentz violation is studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange. We show the chiral nature of the weak interaction…
Lorentz Violation and Partons
Nathan Sherrill
A parton-model description of high-energy hadronic interactions in the presence of Lorentz violation is presented. This approach is used to study lepton-hadron and hadron-hadron in…
Lorentz and CPT Violation in Partons
Alan Kostelecky, Enrico Lunghi, Nathan Sherrill +1
A framework is presented for the factorization of high-energy hadronic processes in the presence of Lorentz and CPT violation. The comprehensive effective field theory describing L…
Lorentz violation and the electron-ion collider
Enrico Lunghi, Nathan Sherrill
We investigate the prospects for detecting violations of Lorentz symmetry in unpolarized deep inelastic electron-proton scattering in the context of the future electron-ion collide…
