Pseudorapidity (Equation Present) distributions of charged particles produced in protonâproton collisions at a centre-of-mass energy of 8(Equation Present) are measured in the ranges (Equation Present) and (Equation Present) covered by the CMS and TOTEM detectors, respectively. The data correspond to an integrated luminosity of (Equation Present). Measurements are presented for three event categories. The most inclusive category is sensitive to 91â96Â % of the total inelastic protonâproton cross section. The other two categories are disjoint subsets of the inclusive sample that are either enhanced or depleted in single diffractive dissociation events. The data are compared to models used to describe high-energy hadronic interactions. None of the models considered provide a consistent description of the measured distributions.

Abstract
Pseudorapidity (Equation Present) distributions of charged particles produced in protonâproton collisions at a centre-of-mass energy of 8(Equation Present) are measured in the ranges (Equation Present) and (Equation Present) covered by the CMS and TOTEM detectors, respectively. The data correspond to an integrated luminosity of (Equation Present). Measurements are presented for three event categories. The most inclusive category is sensitive to 91â96Â % of the total inelastic protonâproton cross section. The other two categories are disjoint subsets of the inclusive sample that are either enhanced or depleted in single diffractive dissociation events. The data are compared to models used to describe high-energy hadronic interactions. None of the models considered provide a consistent description of the measured distributions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
