Description
1. Strangeness and quark-gluon plasma
by J. Rafelski (Uni. of Arizona)
We explore the role of strangeness in the properties and observables of the QGP phase. Chemical over saturation of strangeness degree of freedom may influence the nature of, and location of the phase boundary between deconfined and confined phases. Dynamical calculations of strangeness production tuned to describe RHIC results indicates that this may occur at LHC. We will further discuss the soft hadron and heavy flavor particle observables of strangeness in QGP.
2. Jet properties from di-hadron correlations in pp collisions at sqrt(s) 200 GeV
by J. Rak (JYFL/HIP Finland and Univ. of New Mexico USA)
The properties of jets produced in pp collisions at sqrt(s)=200 GeV are measured using the method of two particle correlations. The trigger particle is a leading particle from a large transverse momentum jet while the associated particle comes from either the same jet or the away-side jet.
The width of the away-side peak is shown to be a convolution of the jet fragmentation transverse momentum j_T with the fragmentation variable, z, and the partonic transverse momentum, k_T. The extraction of these quantities from the combined analysis of the single inclusive and trigger associated cross section will be discussed.
