Description
The ALICE experiment at LHC is designed to study the quark-gluon
plasma (QGP) created in ultra-relativistic heavy ion collisions. The Muon
Forward Tracker (MFT) project is a part of the ALICE program of detector
upgrade for Runs 3 and 4, starting from 2020. The MFT is designed as a
silicon pixel detector covering the -3.6 < η < -2.5 region in the Muon
Spectrometer acceptance to be installed between collision point and the
hadron absorber. Owing to this new detector, the resolution for the
measurement of the muon production vertex will be improved dramatically
and a broader physics program could be developed improving the
performance of the current muon spectrometer.
One of the main goals of the MFT project is to perform measurements
providing information on the restoration of chiral symmetry in the QGP, as
predicted by lattice QCD calculations. Properties of low-mass vector mesons
(ρ,ω,φ) composed of light u, d and s quarks are expected to change under the
chiral symmetry restoration. This phenomenon can’t be easily observed in
hadronic decay channels because of final-state re-interactions of the decay
particles in the later stages of the collisions. For this reason, dilepton
measurements are preferred, allowing the information from the hot and
dense QGP phase to be extracted without significant degradation. In this
contribution, the performance for low-mass dimuon measurements physics
will be presented.
