The decay B^{±}→K_{S}^{0}π^{±}, with a CP asymmetry expected to be close to zero in the standard model, is theoretically clean and sensitive to potential new physics. An analysis of the decays B^{±}→K_{S}^{0}π^{±} and B^{±}→K_{S}^{0}K^{±} is performed using proton-proton collision data collected by …

The first measurement of the $CP$ asymmetry of the decay rate ($A_{CP}$) and the $CP$ average ($ΣA_{\text{FB}}$) and $CP$ asymmetry ($ΔA_{\text{FB}}$) of the forward-backward asymmetry in the muon system of $\mathitΛ^+_c\to pμ^+μ^-$ decays is reported. The measurement is performed using a data …

The decays of the $χ_{b1}(1P)$, $χ_{b2}(1P)$, $χ_{b1}(2P)$ and $χ_{b2}(2P)$ mesons into the $Υ(1S)μ^+μ^-$ final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9fb$^{-1}$. The newly observed decays …
