The Status of Parton Saturation and the CGC

Jean-Paul Blaizot

This is a personal summary of the meeting "Saturation, the Color Glass Condensate and Glasma: What Have we Learned from RHIC?" that took place at BNL in May 2010. The purpose of th…

Asymmetric 1+1-dimensional hydrodynamics in collision

Andrzej Bialas, Robi Peschanski

The possibility that particle production in high-energy collisions is a result of two asymmetric hydrodynamic flows is investigated, using the Khalatnikov form of the 1+1-dimension…

Gaps between jets in hadronic collisions

O. Kepka, C. Marquet, C. Royon

We propose a model to describe diffractive events in hadron-hadron collisions where a rapidity gap is surrounded by two jets. The hard color-singlet object exchanged in the t-chann…

Hydrodynamic obstruction to bubble expansion

Thomas Konstandin, Jose M. No

We discuss a hydrodynamic obstruction to bubble wall acceleration during a cosmological first-order phase transition. The obstruction results from the heating of the plasma in the…

CGC and initial state effects in Heavy Ion Collisions

Javier L Albacete

A brief review of the phenomenological studies in the field of heavy ion collisions based on the Color Glass Condensate theory and, in particular, of those relying in the use of th…

Experimental aspects of diffraction in hadronic physics

Laurent Schoeffel

The most important results on subnuclear diffractive phenomena obtained at HERA and Tevtaron are reviewed and new issues in nucleon tomography are discussed. Some challenges for un…

Jet Reconstruction in Heavy Ion Collisions

Matteo Cacciari, Juan Rojo, Gavin P. Salam +1

We examine the problem of jet reconstruction at heavy-ion colliders using jet-area-based background subtraction tools as provided by FastJet. We use Monte Carlo simulations with an…

Non-resonant New Physics in Top Pair Production at Hadron Colliders

Céline Degrande, Jean-Marc Gérard, Christophe Grojean +2

We use top quark pair production as a probe of top-philic non-resonant new physics. Following a low energy effective field theory approach, we calculate several key observables in…

The ridge in proton-proton collisions at the LHC

Adrian Dumitru, Kevin Dusling, Francois Gelis +3

We show that the key features of the CMS result on the ridge correlation seen for high multiplicity events in sqrt(s)=7TeV proton-proton collisions at the LHC can be understood in…

Exact renormalization group and Phi-derivable approximations

Jean-Paul Blaizot, Jan M. Pawlowski, Urko Reinosa

We show that the so-called Phi-derivable approximations can be combined with the exact renormalization group to provide efficient non-perturbative approximation schemes. On the one…

Role of quantum fluctuations in a system with strong fields: Onset of hydrodynamical flow

K. Dusling, T. Epelbaum, F. Gelis +1

Quantum fluctuations are believed to play an important role in the thermalization of classical fields in inflationary cosmology but their relevance for isotropization/thermalizatio…

Single and double inclusive particle production in d+Au collisions at RHIC, leading twist and beyond

Javier L. Albacete, Cyrille Marquet

We discuss the evidence for the presence of QCD saturation effects in the data collected in d+Au collisions at RHIC. In particular we focus our analysis on forward hadron yields an…

Optimal jet radius in kinematic dijet reconstruction

Gregory Soyez

Obtaining a good momentum reconstruction of a jet is a compromise between taking it large enough to catch the perturbative final-state radiation and small enough to avoid too much…
