Jet Fragmentation Function Moments in Heavy Ion Collisions / Cacciari, Matteo (Paris, LPTHE ; Diderot U., Paris) ; Quiroga-Arias, Paloma (Paris, LPTHE) ; Salam, Gavin P. (Paris, LPTHE ; CERN ; Princeton U.) ; Soyez, Gregory (Saclay, SPhT)
The nature of a jet's fragmentation in heavy-ion collisions has the potential to cast light on the mechanism of jet quenching. However the presence of the huge underlying event complicates the reconstruction of the jet fragmentation function as a function of the momentum fraction z of hadrons in the jet. [...]

Delineating the saturation boundary: linear vs non-linear QCD evolution from HERA data to LHC phenomenology / Quiroga-Arias, Paloma (Paris, LPTHE) ; Albacete, Javier L. (Orsay, IPN ; IPhT, Saclay) ; Milhano, J.Guilherme (Lisbon, CENTRA ; CERN) ; Rojo, Juan (CERN)
The forthcoming p+Pb run at the LHC will provide crucial in formation on the initial state effects of heavy ion collisions and on the gluon saturation phenomena. In turn, most of the saturation inspired phenomenology in heavy ion collisions borrows substantial empiric information from the analysis of e+p data, where abundant high quality data on the small-x kinematic region is available. [...]

Out of Medium Fragmentation from Long-Lived Jet Showers / Casalderrey-Solana, Jorge (Barcelona U., ECM ; CERN) ; Milhano, Jose Guilherme (Lisbon, CENTRA ; Lisbon, IST ; CERN) ; Quiroga-Arias, Paloma (Paris, LPTHE)
We study the time structure of vacuum jet evolution via a simple uncertainty principle estimate in the kinematic range explored by current heavy ion collisions at the LHC. We observe that a large fraction of the partonic splittings occur at large times, of the order of several fm. [...]

AAMQS: a non-linear QCD description of new HERA data at small-x / Quiroga-Arias, Paloma (Paris, LPTHE) ; Albacete, Javier L. (Saclay, SPhT) ; Armesto, N. (Santiago de Compostela U., IGFAE ; Santiago de Compostela U.) ; Milhano, Jose Guilherme (Lisbon, CENTRA ; CERN) ; Salgado, Carlos A. (Santiago de Compostela U., IGFAE ; Santiago de Compostela U.)
We present a global analysis of available data on inclusive structure functions measured in electron-proton scattering at small values of Bjorken-x, including the latest data from the combined HERA analysis on reduced cross sections. Our approach relies on the dipole formulation of DIS together with the use of the non-linear running coupling BK equation for the description of the small-x dynamics. [...]

AAMQS: A non-linear QCD analysis of new HERA data at small-x including heavy quarks / Albacete, Javier L. (Saclay, SPhT) ; Armesto, Nestor (Santiago de Compostela U., IGFAE ; Santiago de Compostela U.) ; Milhano, Jose Guilherme (Lisbon, CENTRA ; CERN) ; Quiroga-Arias, Paloma (Paris, LPTHE) ; Salgado, Carlos A. (Santiago de Compostela U., IGFAE ; Santiago de Compostela U.)
We present a global analysis of available data on inclusive structure functions and reduced cross sections measured in electron-proton scattering at small values of Bjorken-x, x<0.01, including the latest data from HERA on reduced cross sections. Our approach relies on the dipole formulation of DIS together with the use of the non-linear running coupling BK equation for the description of the small-x dynamics. [...]

Testing factorization in pA collisions at the LHC / Quiroga-Arias, Paloma (Santiago de Compostela U. ; Santiago de Compostela U., IGFAE) ; Milhano, Jose Guilherme (Lisbon, CENTRA ; Lisbon, IST ; CERN) ; Wiedemann, Urs Achim (CERN)
Global perturbative QCD analyses, based on large data sets from e-p and hadron collider experiments, provide tight constraints on the parton distribution function (PDF) in the proton. The extension of these analyses to nuclear parton distributions (nPDF) has attracted much interest in recent years. [...]
