Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation

A. Yu. Petrov, M. Schreck, A. R. Vieira

Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators $\hat{m}$ and ${\hat{a}}^{\hat{I}}¼$ in the fermion sector. Both th…
