Uncorrected OS dimuon <pT> versus mass at forward rapidity in PbPb collisions at 5.02 TeV, for dimuon pT < 0.3 GeV/c and 4 centrality intervals (0-10%, 30-50%, 50-70%, 70-90%). The centrality range 10-30% overlapping with the centrality range 0-10% is not shown.
137 runs QA selected of the AOD175 set from the 2015 Run-2 Pb–Pb data taking at 5.02 TeV
LHC15o period and muon calo pass 1 reconstruction
Physics Selection applied
Trigger selection : CMUL7-B-NOPF-MUFAST
Standard cuts are applied on the muon track selections:
- 4 < eta < -2.5 on both muons belonging to the dimuon
- 170 < theta_abs < 178 degree on both muons, where theta_abs is the polar angle of the muon track at the end of the absorber
- Both muon tracks reconstructed in the tracking chambers should match a trigger track reconstructed in the trigger system, above the low pT trigger threshold
- Both muon tracks must pass the pxDCA cut set at 6 sigma
Rapidity selection is applied on the dimuon candidates : 2.5 < y < 4.
