Measurement of multi-particle azimuthal correlations in pp, p + Pb and low-multiplicity Pb + Pb collisions with the ATLAS detector
Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in pp collisions at √ s = 5.02 and 13 TeV and in p + Pb collisions at √ sNN = 5.02 TeV, and compared to the results obtained for low-multiplicity Pb + Pb collisions at √ sNN = 2.76 TeV. These measurements aim to assess the collective nature of particle production. The...

Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in [Formula: see text] collisions at [Formula: see text] = 5.02 and 13 TeV and in [Formula: see text] + Pb collisions at [Formula: see text] = 5.02 TeV, and compared to the results obtained for low-multiplicity [Formula: see text] collisions at [Formula: see text] = 2...
متن کاملMultiplicity distributions in rapidity for Pb-Pb and p-Pb central collisions from a simple model
In the String Percolation Model [1] the particle density is proportional, once the colour reduction factor is taken into account, to the average number of participants ρ ∝ NA; the normalized particle density at mid-rapidity is related to the gluon distribution at small Bjorken-x, ρ ∝ exp ; and the dense-dilute separation scale decreases, from energy conservation, linearly with Y , ∆0 = −αY with...
متن کاملRidge correlation structure in high-multiplicity pp collisions with CMS
Abstract Results on two-particle angular correlations are presented in proton–proton collisions at center of mass energies of 7 TeV, over a broad range of pseudorapidity and azimuthal angle. In very high-multiplicity events at 7 TeV, a pronounced structure emerges in the two-dimensional correlation function for particle pairs with intermediate pT of 1–3 GeV/c, in the kinematic region 2.0 < | η|...
متن کاملFORWARD-BACKWARD MULTIPLICITY CORRELATIONS IN e+e− ANNIHILATION AND pp COLLISIONS AND THE WEIGHTED SUPERPOSITION MECHANISM
Forward-backward multiplicity correlations in symmetric collisions are calculated independently of the detailed form of the corresponding multiplicity distribution. Applications of these calculations to ee annihilation and pp̄ collisions confirm the existence of the weighted superposition mechanism of different classes of substructures or components. When applied to pp̄ collisions in particular, ...
