Stringent limits on $C\!PT$- and Lorentz-invariance violation from $B_s^0$ meson decays
LHCb collaboration, R. Aaij, M. Abdelfatah, A. S. W. Abdelmotteleb et autres
Tests of fundamental symmetries, such as $C\!PT$ and Lorentz invariance, provide sensitive probes of physics beyond the standard quantum-field-theory framework. Possible violations of these symmetries are investigated through interference effects in decays of $B_s^0$ mesons to $D_s^-π^{+}$ states. The analysis uses proton-proton …
