CERN-ATLAS deneyinde S= 13 TeV kütle merkezi enerjisi verisiyle B+ mezon üretim tesir kesitinin ölçülmesi

The differential cross section of B+ meson is presented as a function of transverse momentum and pseudorapidity. It is determined from the channel B+ ->J/psi K+ and reconstructed with using ATLAS pp collision dataset, Run2 2015 data with integrated luminosity of 3.2 fb-1. Measurement is done for 8 intervals of transverse momentum pT and 4 intervals of rapidity |y| covering the range 9 GeV < pT< 120 GeV and |y|< 2.25. B+ / B- ratio is consistent with MC and 13 TeV / 7 TeV cross-section ratio is consistent with the theoretical expectations.
