Heavy-flavour jet production and correlations with ALICE

TL;DR

This paper presents recent measurements of heavy-flavour jet production and correlations in proton-proton and proton-lead collisions at the LHC, including comparisons with theoretical models and first-time measurements of certain jet-momentum fractions.

Contribution

It reports new measurements of heavy-flavour jet properties, including the first measurement of the jet-momentum fraction carried by the $ m{ extLambda_c^+}$ baryon at the LHC, and compares these with theoretical predictions.

Findings

Measurement of D meson jet momentum fraction at 5.02 and 13 TeV

First measurement of $ m{ extLambda_c^+}$ baryon momentum fraction in jets

Nuclear modification factor of heavy-flavour jets in p-Pb collisions

Abstract

This contribution focuses on the latest studies of heavy-flavour jets performed with the ALICE detector. The measurements of the jet momentum fraction carried by the D meson in pp collisions at $\sqrt{s}=5.02$ TeV and $13\ \mathrm{TeV}$ will be presented. The comparison to POWHEG+PYTHIA will be shown. Moreover, the first measurement at the LHC of the jet-momentum fraction carried by the $\mathrm{\Lambda_c^+}$ baryon in pp collisions at $\sqrt{s}=13\ \mathrm{TeV}$ will be reported. Production of heavy-flavour jets in pp collisions at $\sqrt{s}=5.02\ \mathrm{TeV}$ will be also addressed with charged jets tagged by heavy-flavour hadron decay electrons and beauty-hadron decay vertices. The nuclear modification factor of heavy-flavour tagged jets in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\ \mathrm{TeV}$ will be presented.
