Thermodynamical string fragmentation

N Fischer, T Sjöstrand - Journal of High Energy Physics, 2017 - Springer
A bstract The observation of heavy-ion-like behaviour in pp collisions at the LHC suggests
that more physics mechanisms are at play than traditionally assumed. The introduction eg of …

V Khachatryan, AM Sirunyan, A Tumasyan, W Adam… - Physical Review C, 2017 - APS
Two-particle correlations in p Pb collisions at a nucleon-nucleon center-of-mass energy of

Review of jet measurements in heavy ion collisions

M Connors, C Nattrass, R Reed, S Salur - arXiv preprint arXiv:1705.01974, 2017 - arxiv.org
A hot, dense medium called a Quark Gluon Plasma (QGP) is created in ultrarelativistic heavy
ion collisions. Hard parton scatterings generate high momentum partons that traverse the …

Azimuthal anisotropy in particle distribution in a multiphase transport model

S Sarkar, P Mali, A Mukhopadhyay - Physical Review C, 2017 - APS
Anisotropic flow of hadronic matter is considered a sensitive tool to detect the early-stage
dynamics of high-energy heavy-ion collisions. Taking the event-by-event fluctuations of the …

A CGC/saturation approach for angular correlations in proton–proton scattering

E Gotsman, E Levin, I Potashnikova - The European Physical Journal C, 2017 - Springer
We generalized our model for the description of hard processes, and calculate the value of
the azimuthal angular correlations (Fourier harmonics v_n vn), for proton–proton scattering …

Perturbative QCD and beyond: Azimuthal angle correlations in deuteron-deuteron scattering from Bose-Einstein correlations

E Gotsman, E Levin - Physical Review D, 2017 - APS
In this paper, we find, within the framework of perturbative QCD, that in deuteron-deuteron
scattering Bose-Einstein correlations, due to production of two-parton showers, induce …

Bose-Einstein correlations in perturbative QCD: dependence on multiplicity

E Gotsman, E Levin - Physical Review D, 2017 - APS
In this paper we study the dependence of Bose-Einstein correlations on the multiplicity of an
event. We find that events with large multiplicity stem from the production of several-parton …
