First branching fraction measurement of the suppressed decay $Ξ_{c}^{0} \to π^{-} Λ_{c}^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The $Ξ_{c}^{0}$ baryon is unstable and usually decays into charmless final states by the $c \to s u d$ transition. It can, however, also disintegrate into a $π^{-}$ meson and a…

Search for $C P$ violation and observation of $P$ violation in $Λ_{b}^{0} \to p π^{-} π^{+} π^{-}$ decays

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

A search for $C P$ violation in the $Λ_{b}^{0} \to p π^{-} π^{+} π^{-}$ decay is performed using LHCb data corresponding to an integrated luminosity of 6.6 $f b^{- 1}$ collected in $pp$ coll…

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…

Report from RAMP challenge on fast vertexing

Florian Reiss

Reconstructing the vertices of primary interactions at the LHCb experiment is an essential part of its online data acquisition sequence. The quest for ever higher rates and luminos…

Observation of two resonances in the $Λ_{b}^{0} π^{\pm}$ systems and precise measurement of $Σ_{b}^{\pm}$ and $Σ_{b}^{*\pm}$ properties

LHCb collaboration, R. Aaij, C. Abellán Beteta +837

The first observation of two structures consistent with resonances in the final states $Λ_{b}^{0} π^{-}$ and $Λ_{b}^{0} π^{+}$ is reported using samples of $pp$ collision data collected by the…

Study of $Υ$ production in $p$ Pb collisions at $s_{N N} = 8.16$ TeV

LHCb collaboration, R. Aaij, C. Abellán Beteta +840

The production of $Υ (n S)$ mesons ( $n = 1, 2, 3$ ) in $p$ Pb and Pb $p$ collisions at a centre-of-mass energy per nucleon pair $s_{N N} = 8.16$ TeV is measured by the LHCb experiment,…
