Contribution

First measurement of heavy-flavour decay electron correlations with charged particles in pp collisions at 5.02 TeV, compared with PYTHIA simulations.

Findings

Charged particle yields in correlation peaks are consistent with PYTHIA predictions.

Correlation peak widths are measured and compared with models.

Results enhance understanding of heavy-quark hadronization processes.

Abstract

Two-particle azimuthal correlations of electrons from heavy-flavour hadron decays with charged particles can give insight into the properties of heavy-quark production and hadronization into heavy-flavour jets.\\ In this contribution, the ALICE results measured in pp collisions at 5.02 TeV, collected in the LHC Run 2, are presented. The yields of charged particles in the near and away-side correlation peaks and the peak width are compared with PYTHIA calculations.
