WebbAbstract. Described in this paper is a new method for determining the non-diffractive part of the inelastic proton-proton cross section, at the LHC centre of mass energy of 14 14 14 14 TeV. The method is based on counting the number of inelastic proton-proton interactions in the collision regions. Cross sections depend strongly on the incoming particle speed. In the case of a beam with multiple particle speeds, the reaction rate R is integrated over the whole range of energy: $${\displaystyle R=\int _{E}N\,\Phi (E)\,\sigma (E)\,dE}$$ Where σ(E) is the continuous cross section, Φ(E) the differential flux and N the … Visa mer In nuclear physics, the concept of a neutron cross section is used to express the likelihood of interaction between an incident neutron and a target nucleus.
