Workshop on proton-nucleus collisions at the LHC

6 May 2013, 08:45 → 10 May 2013, 16:00 Europe/Zurich

ECT* Trento

David d'Enterria (CERN), Francois Arleo (LAPTH, Annecy-le-Vieux)

The first proton–lead collisions run at the CERN Large Hadron Collider (LHC) takes place in Jan-Feb 2013 after a successful pilot run of Sept 2012.
The aim of this ECT* (Trento) workshop is to discuss experimental and theoretical issues connected to the physics of proton-nucleus collisions at the LHC. The first results obtained by the ALICE, ATLAS, CMS, LHCb, LHCf and TOTEM experiments will be discussed as well as the future measurements to be carried out. The main topics of the workshop include:
• p–A benchmark measurements for interpreting A–A collisions results.
• Constraints of nuclear parton distributions functions (PDF),
• Small-x QCD and gluon saturation physics,
• Forward physics, diffractive and electromagnetic (ultra-peripheral) collisions,
• Impact of collider p–A measurements for ultra-high energy cosmic rays physics.

17:00 → 18:00 Thermalization of the quark-gluon plasma and Bose-Einstein condensation in unusual circumstances

In this talk, I shall focus on a particular phenomenon that could play a role in the process of thermalization, namely the strong amplification of very soft gluon modes, possibly leading to the formation of a transient Bose-Einstein condensate. Aside from its potential relevance to the thermalization problem, the formation of such a condensate in relativistic systems is an interesting problem in itself. The onset of condensation in such systems has been studied recently using kinetic theory in the approximation of small scattering angles. Numerical evidences for the scaling regime that develops near the onset of condensation will be presented.
