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…
Concepts in Lorentz and CPT Violation
Alan Kostelecky
This contribution to the CPT'22 meeting provides a brief review of some concepts in Lorentz and CPT violation.
Developments in Lorentz and CPT Violation
Alan Kostelecky
This talk at the CPT'19 meeting outlines a few recent developments in Lorentz and CPT violation, with particular attention to results obtained by researchers at the Indiana Univers…
Searching for CPT Violation with Neutral-Meson Oscillations
Benjamin R. Edwards, Alan Kostelecky
A general technique is presented for treating CPT violation in neutral-meson oscillations. The effective field theory for a complex scalar with CPT-violating operators of arbitrary…
Gauge field theories with Lorentz-violating operators of arbitrary dimension
Alan Kostelecky, Zonghao Li
The classification of Lorentz- and CPT-violating operators in nonabelian gauge field theories is performed. We construct all gauge-invariant terms describing propagation and intera…
Lorentz-violating spinor electrodynamics and Penning traps
Yunhua Ding, Alan Kostelecky
The prospects are explored for testing Lorentz- and CPT-violating quantum electrodynamics in experiments with Penning traps. We present the Lagrange density of Lorentz-violating sp…
