Limits on Lorentz violation from charged-pion decay
arXiv:1404.7629 · doi:10.1103/PhysRevD.89.101702
Abstract
Charged-pion decay offers many opportunities to study Lorentz violation. Using an effective field theory approach, we study Lorentz violation in the lepton, W-boson, and quark sectors and derive the differential pion-decay rate, including muon polarization. Using coordinate redefinitions we are able to relate the first-generation quark sector, in which no bounds were previously reported, to the lepton and W-boson sector. This facilitates a tractable calculation, enabling us to place bounds on the level of on first-generation quark parameters. Our expression for the pion-decay rate can be used to constrain Lorentz violation in future experiments.
