Allen: A high level trigger on GPUs for LHCb

R. Aaij, J. Albrecht, M. Belous +26

We describe a fully GPU-based implementation of the first level trigger for the upgrade of the LHCb detector, due to start data taking in 2021. We demonstrate that our implementati…

Test of lepton universality with $Λ_{b}^{0} \to p K^{-} ℓ^{+} ℓ^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +904

The ratio of branching fractions of the decays $Λ_{b}^{0} \to p K^{-} e^{+} e^{-}$ and $Λ_{b}^{0} \to p K^{-} μ^{+} μ^{-}$ , $R_{p K}^{- 1}$ , is measured for the first time using proton-proto…

Isospin amplitudes in $Λ_{b}^{0} \to J / ψ Λ (Σ^{0})$ and $Ξ_{b}^{0} \to J / ψ Ξ^{0} (Λ)$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +902

Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. We…

Precision measurement of the $Ξ_{cc}^{++}$ mass

LHCb collaboration, R. Aaij, C. Abellán Beteta +901

A measurement of the $Ξ_{cc}^{++}$ mass is performed using data collected by the LHCb experiment between 2016 and 2018 in $pp$ collisions at a centre-of-mass energy of 13 TeV, corr…

Determination of quantum numbers for several excited charmed mesons observed in $B^{-} \to D^{*+} π^{-} π^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +907

A four-body amplitude analysis of the $B^{-} \to D^{*+} π^{-} π^{-}$ decay is performed, where fractions and relative phases of the various resonances contributing to the decay are measu…
