Measurement of the inclusive J/ψ polarization at forward rapidity in pp collisions at √s = 8 TeV
(2018) [Artigo de periódico]We report on the measurement of the inclusive J/ψ polarization parameters in pp collisions at a center of mass energy √ s = 8 TeV with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to ... -
Prompt and non-prompt J/ψ production and nuclear modification at mid-rapidity in p–Pb collisions at √sNN=5.02 TeV
(2018) [Artigo de periódico]A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon–nucleon centre-of-mass energy √ sNN = 5.02 TeV is presented. The semi-inclusive decay channel of beauty hadrons into J/ψ is ... -
Prompt J/[psi] production at the LHC
(2002) [Artigo de periódico]Models with essential non-perturbative QCD dynamics for the production of charmonium are extrapolated to give predictions of prompt J/v production at the LHC. Differences of up to an order of magnitude occurs, although the ... -
Scaling function for the production of vector mesons and DVCS in the saturation scheme

Search for collectivity with azimuthal J/ψ-hadron correlations in high multiplicity p–Pb collisions at √sNN=5.02 and 8.16 TeV
(2018) [Artigo de periódico]We present a measurement of azimuthal correlations between inclusive J/ψand charged hadrons in p–Pbcollisions recorded with the ALICE detector at the CERN LHC. The J/ψare reconstructed at forward (p-going, 2.03 <y <3.53) ... -
Search for rare decays of Z and Higgs bosons to J/ψ and a photon in proton-proton collisions at √s = 13TeV
(2019) [Artigo de periódico]A search is presented for decays of Z and Higgs bosons to a J/ψ meson and a photon, with the subsequent decay of the J/ψ to μ + μ −. The analysis uses data from proton-proton collisions with an integrated luminosity of ... -
Studies of J/ψ production at forward rapidity in Pb–Pb collisions at √sNN = 5.02 TeV
(2020) [Artigo de periódico]The inclusive J/ψ production in Pb–Pb collisions at the center-of-mass energy per nucleon pair √sNN = 5.02 TeV, measured with the ALICE detector at the CERN LHC, is reported. The J/ψ meson is reconstructed via the dimuon ... -
Study of J/ψ azimuthal anisotropy at forward rapidity in Pb-Pb collisions at √sNN = 5.02 TeV
(2019) [Artigo de periódico]The second (v2) and third (v3) ow harmonic coe cients of J/ mesons are measured at forward rapidity (2:5 < y < 4:0) in Pb-Pb collisions at p sNN = 5.02TeV with the ALICE detector at the LHC. Results are obtained with the ... -
Study of J/ψ meson production inside jets in pp collisions at √s = 8 TeV
(2020) [Artigo de periódico]A study of the production of prompt J/ψ mesons contained in jets in proton-proton collisions at √s = 8 TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb−1 collected with ... -
The color evaporation model in diffractive J/[Psi] photoproduction
(1999) [Artigo de periódico]Our goal is the study of color effects on the J/[Psi] mesons production, as well as the study of their elastic production. We use the color evaporation model CEM, where a single factor takes into account the probability ... -
The QCD pomeron in ultraperipheral heavy ion collisions : I. The double J/Ψ production
(2003) [Artigo de periódico]The contribution of the QCD pomeron to the process AA → AAJ/Ψ J/Ψ is discussed. We focus on the photon–photon collision, with the quasi-real photon coming from theWeizs¨acker–Williams spectrum of the nuclei. We calculate ... -
Vector meson production in coherent hadronic interactions : update on predictions for energies available at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider
(2011) [Artigo de periódico]In this Rapid Communication we update our predictions for the photoproduction of vector mesons in coherent pp and AA collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies using the ...
