Pseudorapidity distribution of charged hadrons in proton–proton collisions at vs=13TeV

Abstract: The pseudorapidity distribution of charged hadrons in pp collisions at vs=13TeV is measured using a data sample obtained with the CMS detector, operated at zero magnetic field, at the CERN LHC. The yield of primary charged long-lived hadrons produced in inelastic pp collisions is determined in the central region of the CMS pixel detector (|?| <2) using both hit pairs and reconstructed tracks. For central pseudorapidities (|?| <0.5), the charged-hadron multiplicity density is dNch/d?||?|<0.5=5.49 ±0.01 (stat)±0.17 (syst), a value obtained by combining the two methods. The result is compared to predictions from Monte Carlo event generators and to similar measurements made at lower collision energies.
