Studying the potential of Graphcore IPUs for applications in Particle Physics

Lakshan Ram Madhan Mohan, Alexander Marshall, Samuel Maddrell-Mander +5

This paper presents the first study of Graphcore's Intelligence Processing Unit (IPU) in the context of particle physics applications. The IPU is a new type of processor optimised…

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…

Study of the $ψ_{2} (3823)$ and $χ_{c 1} (3872)$ states in $B^{+} \to (J ψ π^{+} π^{-}) K^{+}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +956

The decays $B^{+} \to J / ψ π^{+} π^{-} K^{+}$ are studied using a data set corresponding to an integrated luminosity of 9fb $^{- 1}$ collected with the LHCb detector in proton-proton co…
