Measurement of the forward charged particle pseudorapidity density in pp collisions at sqrt(s) = 8 TeV

The TOTEM experiment has measured the pseudorapidity density of charged particles with transverse momentum above 40 MeV/c in pp collisions at sqrt(s) = 8 TeV for 5.3 < |eta| < 6.4 in a low intensity run with common data taking with the CMS experiment. The measurement has been made for three different events categories: an inclusive one with at least one charged particle in either −6.5 < eta < −5.3 or 5.3 < eta < 6.5, a non-single diffractive enhanced one with at least one charged particle in both −6.5 < eta < −5.3 and 5.3 < eta < 6.5 and a single diffractive enhanced one with at least one charged particle in −6.5 < eta < −5.3 and none in 5.3 < eta < 6.5 or vice-versa.
