  1. 122. Why mean pt is interesting
    Prof. Michal Praszalowicz (Jagiellonian University)
    14/09/2014, 17:20
    Saturation
    We review recent ALICE data on mean pt in pp and in pPb collisions. First we show that multiplicity spectra exhibit geometrical scaling (GS) and then we study its consequences as far as mean pt is concerned. Next we discuss appropriate scaling variable for mean pt dependence on N_ch which is related to the interaction radius R. We use Color Glass Condensate results for R dependence on...

  2. 126. On parton number fluctuations at various stages of the rapidity evolution
    Dr Stéphane Munier (CPHT, Ecole Polytechnique, CNRS)

    Saturation
    Starting with the interpretation of parton evolution with rapidity as a branching-diffusion process, we describe the different kinds of fluctuations of the density of partons which affect the properties of QCD scattering amplitudes at moderately high energies. We then derive some of these properties as direct consequences of the stochastic picture. We get new results on the expression of the...

  3. 134. Large impact parameter behaviour and CGC/saturation approach: the BFKL equation with massive gluon
    Prof. Eugene Levin (Tel Aviv University/UTFSM)

    Saturation
    I will discuss the solution to the BFKL equation with massive gluon.Such equation arises in the electro-weak theory with the zero Weinberg angle . However, for us, the gauge invariant theory with the Higgs mechanism for the creation of mass gives the instructive example of the theory in which has correct large impact parameter behaviour. The spectrum of this equation which coincide with...

  4. 139. Next-to-leading order corrections for scattering amplitudes in high-energy QCD
    Mr Yair Mulian (PhD student)

    Saturation
    The rapidity (energy) evolution of hadronic observables in scattering of a diluted, perturbative projectile, on a dense gluonic target is described in QCD by the JIMWLK equation. This is a functional non-linear equation that is consistent with the QCD unitarity and reduces to the linear BFKL equation when the scattering probability is low. Recently, there was major progress in this field -...

  5. 166. Particle Production in Dilute-Dense Collisions and Rapidity Correlations
    Mr José Daniel Madrigal Martínez (IPhT CEA Saclay)
    14/09/2014, 18:40
    Saturation
    Multi-particle production with rapidity correlations in high-energy pA collisions can be studied through a generalization of the JIMWLK Hamiltonian applying to a generating functional describing the projectile. We also address the physical picture described by different viewpoints on the evolution equations governing these generating functionals.
