Measurement of the production of charm jets tagged with D-0 mesons in pp collisions at root s=7 TeV
Popis výsledku v původním jazyce
The production of charm jets in proton-proton collisions at a center-of-mass energy of p s = 7TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total integrated luminosity of 6: 23 nb, collected using a minimum-bias trigger. Charm jets are identi fi ed by the presence of a D 0 meson among their constituents. The D 0 mesons are reconstructed from their hadronic decay D 0 ! K. The D 0 -meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-k T algorithm in the jet transverse momentum range 5 < p ch T,jet < 30 GeV= c and pseudorapidity jjetj < 0: 5. The fraction of charged jets containing a D 0 -meson increases with p ch T,jet from 0: 042 0: 004 (stat) 0: 006 (syst) to 0: 080 0: 009 (stat) 0: 008 (syst). The distribution of D 0 -meson tagged jets as a function of the jet momentum fraction carried by the D 0 meson in the direction of the jet axis (z ch jj) is reported for two ranges of jet transverse momenta, 5 < p ch T,jet < 15 GeV= c and 15 < p ch T,jet < 30 GeV= c in the intervals 0: 2 < z ch jj < 1: 0 and 0: 4 < z ch jj < 1: 0, respectively. The data are compared with results from Monte Carlo event generators (PYTHIA 6, PYTHIA 8 and Herwig 7) and with a Next-to-Leading-Order perturbative Quantum Chromodynamics calculation, obtained with the POWHEG method and interfaced with PYTHIA 6 for the generation of the parton shower, fragmentation, hadronisation and underlying event.
