Initial state effects and Color Glass Condensate
Experimental
The electroweak W bosons do not participate in the strong interaction, and thus constitute clean probes of the initial state of nuclear collisions. They provide a unique constraint on the nuclear parton distributions, in particular on the antiquarks from the sea. A first analysis of PbPb data has confirmed the medium-blind characteristic of the electroweak bosons. With the new pPb data,...

Initial state effects and Color Glass Condensate
Theory
We present a phenomenological study of the single- and double-inclusive suppression data of high-pT particles in central Pb-Pb collisions at LHC. The analysis is based on quenching weights for medium-induced gluon radiation computed in the multiple soft scattering approximation and embedded in a hydrodynamic description of the bulk medium.

Jets in the vacuum and in the medium
Experimental
Measurements of high pT processes in ultrarelativistic proton-nucleus collisions are sensitive to changes in the partonic densities arising from the presence of the high-density nuclear environment. Additionally, such measurements serve as a benchmark of the so called "cold nuclear matter" effects, providing the context within which to understand the strong suppression of high pT processes...

Initial state effects and Color Glass Condensate
Experimental
The Z boson is a new probe of ultra-relativistic heavy-ion collisions, which became accessible at the LHC energies. Unambiguously detected when decaying in the dilepton channel, it can help to constrain nuclear parton distribution functions, it can serve as a standard candle for initial state effects, and it represents an in-situ probe for binary scaling in the final state of the collisions....

Initial state effects and Color Glass Condensate
Theory
One of the goals of the proton-lead run at the LHC is to produce a benchmark for heavy-ion collisions. Preliminary analyzes hint that nPDFs fail to give a proper description for certain observables. Here we present a full study of the compatibility between current sets of initial state nuclear distributions and data from the LHC p-Pb run. By means of the Hessian reweighting technique we give a...

Initial state effects and Color Glass Condensate
Theory
The “standard model” of relativistic heavy-ion collisions describes the
early stage of an hadronic collission by the Color Glass Condensate.
The studies of anisotropically expanding plasmas show that non-Abelian
plasmas isotropize fast enough thanks to the Chromo-Weibel instability.
Recent work involves the novel incorporation of quantized fermions in
the semi-classical Yang-Mills evolution.
