Description
The TOTEM experiment has measured the charged-particle pseudorapidity density d N ch /dη in pp collisions at sqrt(s)=7 TeV for 5.3<|η|<6.4 in events with at least one charged particle with transverse momentum above 40 MeV/ c in this pseudorapidity range. This extends the analogous measurement performed by the other LHC experiments to the previously unexplored forward η region. The measurement refers to more than 99% of non-diffractive processes, to single, double diffractive processes with diffractive masses above ~3.4 GeV/ c 2 , corresponding to about 95% of the total inelastic cross-section. The d N ch /dη has been found to decrease with |η|, from 3.84 ± 0.01(stat) ± 0.37(syst) at |η|=5.375 to 2.38±0.01(stat)±0.21(syst) at |η|=6.375. Several MC generators have been compared to data; none of them has been found to fully describe the measurement.
