The
project:
One
of the main goals in the field of high-energy nuclear physics is
to understand the behavior of hadrons and their constituents in
vacuum and under extreme conditions of temperature and density.
Quarks in Nature have never been observed free, but always
confined into hadrons by the gluon field; however inelastic
electron scattering at high momentum transfer indicates that
quarks inside the nucleon behave as point-like non interacting
particles. One prediction of QCD is a phase transition from
standard nuclear matter to a plasma of free quarks and gluons
(Quark Gluon Plasma) at high temperatures and densities. The
necessary conditions of high energy density are experimentally
realized by heavy ion reactions at ultrarelativistic energies.
Among the signatures to study the properties of the QGP, the
suppression of hard partons due to energy loss in the medium
should provide information on the properties of the medium, and on
the interaction between the parton and the medium. Energy loss,
expected to increase with parton color-charge and decrease with
increasing parton mass, leads to a pattern of gradually decreasing
suppression when going from gluon-originated light-flavor hadrons
to charm and to beauty mesons is expected. In addition the
heavy-flavor hadro-chemistry allows to assess the initial
temperature and the degree of thermal equilibration of the
partons, which may cause heavy quarks to thermalize and hadronize
inside the medium via coalescence with another quark from the
medium itself. This project aims to measure beauty and to
disentangle it from charm with the ALICE detector at LHC, using
the new most sophisticated analysis techniques as well as new
detector upgrades. Our objectives combine the experience of the
applicant in the heavy-flavor physics gained at lower energy
experiment at RHIC and the expertise of the host as a leading
institute in the proposed subjects to form and present a coherent
picture of the fundamental properties of nuclear matter.
