摘要: Diffraction in pp collisions contributes approximately 30 % of the inelastic cross section. Its influence on pseudorapidity density is not well constrained at high energy. A method to estimate contributing fractions diffractive events section has been developed, and are measured ALICE detector 900 GeV (7 TeV) be f\(_D\)=0.278\(\pm\)0.055 (f\(_D\)=0.28\(\pm\)0.054) respectively. These results compatible with recent ATLAS measurements. Bjorken’s energy relation suggests that, multiplicity LHC, an environment comparable A-A RHIC could produced. Such great interest Collaboration. Constraints running conditions have established for obtaining a data sample using detector’s trigger. model independent separate distribution from ‘pile-up’ contributions used connection other findings establish suitable threshold It demonstrated obtained under these 3 months can conduct early strangeness analyses multiplicities over 5 times mean. resulted 16 million being date.
