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…
The azimuthal correlation between the leading jet and the scattered lepton in deep inelastic scattering at HERA
ZEUS Collaboration, I. Abt, R. Aggarwal +78
The azimuthal correlation angle, , between the scattered lepton and the leading jet in deep inelastic scattering at HERA has been studied using data collected with…
