Vacuum Cherenkov Radiation for Nonminimal Isotropic Lorentz Violation
Albert Yu. Petrov, Marco Schreck, Alexandre R. Vieira
In this work, we study the effects of vacuum Cherenkov radiation caused by nonminimal dimension-5 Lorentz-violating (LV) operators in the fermion sector. Explicitly, we focus on tw…
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…
Two-loop renormalisation of gauge theories in Implicit Regularisation and connections to dimensional methods
A. Cherchiglia, D. C. Arias-Perdomo, A. R. Vieira +2
We compute the two-loop -function of scalar and spinorial quantum electrodynamics as well as pure Yang-Mills and quantum chromodynamics using the background field method in a fu…
Lorentz-Violating Running of Coupling Constants
A. R. Vieira, N. Sherrill
We compute the full vacuum polarization tensor in the minimal QED extension. We find that its low-energy limit is dominated by the radiatively induced Chern-Simons-like term and th…
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…
