Title: Production and polarization of prompt $J / ψ$ in the improved color evaporation model using the $k_{T}$ -factorization approach

Abstract

We calculate the polarization of prompt $$J/{\psi}$$ production in the improved color evaporation model at leading order employing the $${k}_{T}$$-factorization approach. In this paper, we present the polarization parameter $${{\lambda}}_{{\vartheta}}$$ of prompt $$J/{\psi}$$ as a function of transverse momentum in $p+p$ and $p+A$ collisions to compare with data in the helicity, Collins-Soper and Gottfried-Jackson frames. We also present calculations of the charmonium production cross sections as a function of rapidity and transverse momentum. This is the first $${p}_{T}$$-dependent calculation of charmonium polarization in the improved color evaporation model. We find agreement with both charmonium cross sections and polarization measurements.

$J / ψ$ polarization in high multiplicity $p p$ and $p A$ collisions: $CGC + NRQCD$ approach

Journal Article Stebel, Tomasz ; Watanabe, Kazuhiro - Physical Review D

Quarkonium production mechanism in high multiplicity small collision systems has recently been pursued in the color-glass-condensate (CGC) effective theory combined with non-relativistic QCD (NRQCD) factorization, allowing to study initial state interactions. Quarkonium polarization, potentially measured in future experiments, would help elucidate the quarkonium production mechanism at high multiplicities. In this paper, we provide predictions onmore »« less

Relative Modification of Prompt $ψ (2 S)$ and $J / ψ$ Yields from $p p$ to PbPb Collisions at $\sqrt{s_{N N}} = 5.02 TeV$

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... - Physical Review Letters

The relative modification of the prompt ψ(2S) and J/ψ yields from pp to PbPb collisions, at the center-of-mass energy of 5.02 TeV per nucleon pair, is presented. The analysis is based on pp and PbPb data samples collected by the CMS experiment at the LHC in 2015, corresponding to integrated luminosities of 28.0 pb^-1 and 464 μb^-1, respectively. The double ratio of measured yields of prompt charmonia reconstructed through their decays into muon pairs, (N_ψ(2S)/N_J/ψ)_PbPb/(N_ψ(2S)/N_J/ψ)_pp, is determined as a function of PbPb collision centrality and charmonium transverse momentum p_T, in two kinematic intervals: |y|<1.6 covering 6.5<_pT<30 GeV/c and 1.6<|y|<2.4 covering 3<_pT<30more »« less

Measurement of prompt $ψ (2 S)$ to $J / ψ$ yield ratios in Pb-Pb and $p$ - $p$ collisions at $\sqrt{s_{N N}} = 2.76 TeV$

Journal Article Khachatryan, V. ; Sirunyan, A. M. ; Tumasyan, A. ; ... - Physical Review Letters

The ratio between the prompt ψ(2S) and J/ψ yields, reconstructed via their decays into μ⁺μ^-, is measured in Pb-Pb and p-p collisions at √s_NN=2.76 TeV. Likewise, the analysis is based on Pb-Pb and p-p data samples collected by CMS at the Large Hadron Collider, corresponding to integrated luminosities of 150 μb^-1 and 5.4 pb^-1, respectively. The double ratio of measured yields (N_ψ(2S)/N_J/ψ)_Pb-Pb/(Nψ(2S)/N_J/ψ)_p-p is computed in three Pb-Pb collision centrality bins and two kinematic ranges: one at midrapidity, |y|<1.6, covering the transverse momentum range 6.5_T<30 GeV/c, and the other at forward rapidity, 1.6<|y|<2.4, extending to lower p_T values, 3_T<30 GeV/c.
