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…

Measurement of the $Ω_{b}^{-}$ baryon lifetime

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

The lifetime ratio $r_{τ} \equiv τ_{Ω_{b}^{-}} / τ_{Ξ_{b}^{-}}$ between the $Ω_{b}^{-}$ and $Ξ_{b}^{-}$ baryons is measured using a sample of $pp$ collision data corresponding to an integrated lum…

LHCb collaboration, R. Aaij, M. Abdelfatah +1112

This paper presents the first measurement of the forward-backward asymmetry, $A_{FB}$ , and the flat term, $F_{H}$ , that parameterise the angular distribution of the $B^+\toπ^+μ…
