متن کاملEvidence for collectivity in pp collisions at the LHC
Measurements of twoand multi-particle angular correlations in pp collisions at √ s = 5, 7, and 13 TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of 1.0 pb−1 (5 TeV), 6.2 pb−1 (7 TeV), and 0.7 pb−1 (13 TeV), were collected using the CMS detector at the LHC. The second-order (v2) and third-order (v3) azimuthal anisotropy harmon...
متن کاملPredictions of hadron abundances in pp collisions at the LHC
s = 200 GeV, and extrapolating the overall normalization from pp̄ collisions at the SPS and Tevatron, we find that the expected rapidity densities are almost grand-canonical. Therefore, at LHC the ratios between different species become essentially energy-independent, provided that the hadronization temperature TH and the strangeness suppression factor γS retain the stable values observed in the...
متن کاملOdderon Effects in pp Collisions: Predictions for LHC Energies
We consider the possible contribution of Odderon (Reggeon with αOdd(0) ∼ 1 and negative signature) exchange to the differences in the total cross sections of particle and antiparticle, to the ratios of real/imaginary parts of the elastic pp amplitude, and to the differences in the inclusive spectra of particle and antiparticle in the central region. The experimental differences in total cross s...
