First measurement of the forward rapidity dependence of $W$ boson transverse helicity fractions

LHCb collaboration, R. Aaij, M. Abdelfatah +1160

The transverse helicity fractions of $W$ bosons are measured as a function of the $W$ boson rapidity, $y_{W}$ , in the range $0 \leq y_{W} \leq 5$ using $W \to μ ν_{μ}$ decays in $pp$ co…

Stringent limits on $C P T$ - and Lorentz-invariance violation from $B_{s}^{0}$ meson decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1161

Tests of fundamental symmetries, such as $C P T$ and Lorentz invariance, provide sensitive probes of physics beyond the standard quantum-field-theory framework. Possible violations…
