Abstract (data abstract)
CERN-LHC. First data from the LHC. Measurements of the charged-particle pseudorapidity distributions at centre-of-mass energy 900 GeV in proton proton collisions. The data sample comprise 280 events recorded in the afternoon of 23rd November 2009 during the commissioning of the LHC. The data are analysed as cross sections for i nelastic (INEL) interactions and for non-single-diffractive (NSD) interactions.. Numerical values supplied by Jan Fiete Grosse-Oetringhaus.
