Proton-proton physics in ALICE
The ALICE experiment has several unique features which makes it an important contributor to proton-proton physics at the LHC, in addition to its specific design goal of studying the physics of strongly interacting matter in heavy-ion collisions. The unique capabilities include its low transverse momentum (pt) acceptance, excellent vertexing, particle identification over a broad pt range and jet...
متن کاملPhenomenological analysis connecting proton-proton and antiproton-proton elastic scattering
Based on the behavior of the elastic scattering data, we introduce an almost model-independent parametrization for the imaginary part of the scattering amplitude, with the energy and momentum transfer dependences inferred on empirical basis and selected by rigorous theorems and bounds from axiomatic quantum field theory. The corresponding real part is analytically evaluated by means of dispersi...
متن کاملSlope Analysis for Elastic Proton-proton and Proton-antiproton Scattering
The diffraction slope parameter is investigated for elastic proton-proton and protonantiproton scattering based on the all available experimental data at intermediate square of momentum transfer in the main. Energy dependence of the elastic diffraction slope is approximated by various analytic functions in a model-independent fashion. The expanded standard logarithmic approximations allow to de...
متن کاملStrangeness production in proton - proton and proton - nucleus collisions ∗
In these lectures we discuss the investigation of the strange meson production in protonproton (pp) and in proton-nucleus (pA) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of N(1650), N(1710), and N(1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expe...
متن کاملproton ?
A QCD analysis of ¯ pN → γ * π and ¯ pN → γ * γ Where is the pion in the proton ? We study the scaling regime of nucleon-anti-nucleon annihilation into a deeply virtual photon and a photon or meson, ¯ pN → γ * π, ¯ pN → γ * γ, in the forward direction. The leading twist amplitude factorizes into an antiproton distribution amplitude, a short-distance matrix element and a long-distance dominated ...
