Measurement of the $η_{c} (1 S)$ production cross-section in $pp$ collisions at $s = 13$ TeV

LHCb collaboration, R. Aaij, C. Abellán Beteta +913

Using a data sample corresponding to an integrated luminosity of $2.0 f b^{- 1}$ , collected by the LHCb experiment, the production of the $η_{c} (1 S)$ state in proton-proton collisions…

Updated measurement of decay-time-dependent CP asymmetries in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +910

A search for decay-time-dependent charge-parity ( $C P$ ) asymmetry in $D^{0} \to K^{+} K^{-}$ and $D^{0} \to π^{+} π^{-}$ decays is performed at the LHCb experiment using proton-proton collision d…

Measurement of the mass difference between neutral charm-meson eigenstates

LHCb Collaboration, R. Aaij, C. Abellán Beteta +842

We report a measurement of the mass difference between neutral charm-meson eigenstates using a novel approach that enhances sensitivity to this parameter. We use $2.3 \times 1 0^{6}$ $…
