    Title: Global description of bottomonium suppression in proton-nucleus and nucleus-nucleus collisions at LHC energies
    Author: Ferreiro, Elena
    Contributor: Ferreiro, Elena (pacrepositoryorg)
    Subject: Collisions ; Large Hadron Collider ; Protons ; Nuclei (Nuclear Physics) ; Scattering Cross Sections ; Distribution Functions ; Energy Distribution
    Description: We show that we can reach a global and coherent description of bottomonium suppression in both proton-nucleus and nucleus-nucleus collisions at the LHC energies. The measured relative suppression of the excited bottomonium states as compared to their ground state allows us to constrain the scattering cross sections between the bottomonia and the comovers created during the collisions. Our result hints at a similar energy distribution of these comovers in the environment created by proton-nucleus and nucleus-nucleus collisions. Along the way of our study, we also update our knowledge for the bottomonium feed-down pattern and our comprehension on the modification of the nuclear parton distribution functions in proton-nucleus collisions. We present our results for \(p\)Pb collisions at 5.02 and 8.16 TeV and for PbPb collisions at 2.76 and 5.02 TeV.

    Cold Nuclear Matter effects in Upsilon production in dAu collisions at RHIC

    Title: Cold Nuclear Matter effects in Upsilon production in dAu collisions at RHIC
    Author: Rakotozafindrabe, Andry; Ferreiro, Elena; Fleuret, Frédéric; Lansberg, Jean-Philippe; Matagne, Nicolas
    Contributor: Matagne, Nicolas (pacrepositoryorg)
    Subject: Gluons ; Collisions ; Nuclear Matter ; Energy Dissipation
    Description: We report on our recent study of Cold Nuclear Matter effects on the Upsilon production at RHIC in dAu collisions. The first experimental results available on the nuclear modification factor R_dAu have rather large uncertainties. They nevertheless allow to bring qualitative information on the nature of the nuclear effects at play on top of the usual nuclear absorption, since the latter is expected to lie in a quite small range around a value close to ten times smaller as for charmonia. At backward rapidities, the behavior of R_dAu hints at the presence of a gluon EMC effect, analogous to the quark EMC effect -- but possibly stronger. Mid rapidity measurements with a better precision are highly desirable to pin down the gluon anti-shadowing, still under debate. At forward rapidities, the data leave some room for an additional fractional energy loss mechanism, recently revived in the literature.

    Title: From percolation to the Color Glass Condensate
    Author: Ferreiro, Elena
    Contributor: Ferreiro, Elena (pacrepositoryorg)
    Subject: Glass ; Color ; Percolation ; Saturation (Color) ; Initial Conditions ; Condensates ; Quark-Gluon Plasma
    Description: I review the problem of parton saturation and its implications through three in principal different approaches, but somewhat related: saturation in a geometrical approach, QCD saturation through the Color Glass Condensate and perturbative Pomeron approach with initial conditions. I also make some comments about how that could be related to a Quark Gluon Plasma formation.

    Title: Color strings, Pomerons and Color Glass Condensate
    Author: Ferreiro, Elena
    Contributor: Ferreiro, Elena (pacrepositoryorg)
    Subject: Experiments ; Partons ; Glass ; Color ; Strings ; Pomerons ; Saturation (Color) ; Initial Conditions ; Condensates
    Description: In the recent experiments like DIS at HERA or the heavy-ion experiments at RHIC, and also in expected LHC at CERN, the number of involved partons is very large, due to the high energy and/or the high number of participants of those experiments. These high parton densities should in principal lead to an extremely huge multiparticle production, but experimentally we have seen that this is not the case. So there should be a mechanism that reduces the number of created particle. Here, I review the problem of parton saturation and its implications through three in principal different approaches, but somewhat related: saturation in a geometrical approach, QCD saturation through the Color Glass Condensate and perturbative Pomeron approach with initial conditions.
