Physics of the Muon Spectrometer of the ALICE Experiment
The main goal of the Muon spectrometer of the ALICE experiment at LHC is the
measurement of heavy quark production in p+p, p+A and A+A collisions at LHC
energies, via the muonic channel. Physics motivations and expected performances
have been presented in this talk.Comment: 10 pages and 4 figures. Talk presented in the ICPAQGP Conference,

Temperature and Density Effects on the Nucleon Mass Splitting
The finite temperature and finite density dependence of the neutron-proton
mass difference is analysed in a purely hadronic framework where the
mixing is crucial for this isospin symmetry breakdown. The
problem is handled within Thermo Field Dynamics. The present results,
consistent with partial chiral and charge symmetry restoration, improve the
experimental data fit for the energy difference between mirror nuclei.Comment: 17 pages, revtex fil
Minijets and the Two-Body Parton Correlation
A large number of double parton scatterings have been recently measured by
CDF. The double parton scattering process measures , a non
perturbative quantity related to the hadronic transverse size and with the
dimensions of a cross section. The actual value measured by CDF is considerably
smaller as compared with the naive expectation, namely the value of the
inelastic non diffractive cross section. The small value of may
be an effect of the hadron structure in transverse plane. We discuss the
problem by taking into account, at all orders, the two-body parton correlations
in the many-body parton distributions.Comment: 19 pages, plane tex, no figure
