Abstract (data abstract)
This paper presents isolated photon--hadron correlations usingpp and p$-$Pb data collected by the ALICE detector at the LHC. For photons with $|\eta|<0.67$ and $12 < p_\mathrm{T} < 40$ GeV/$c$, the associated yield of charged particles in the range {$|\eta|<0.80$} and $0.5 < p_\mathrm{T} < 10$ GeV/$c$ is presented. These momenta are much lower than previous measurements at the LHC. No significant difference between pp and p$-$Pb is observed, with Pythia 8.2 describing both data sets within uncertainties. This measurement constrains nuclear effects on the parton fragmentation in p$-$Pb collisions, and provides a benchmark for future studies of Pb$-$Pb collisions.
