ƒÖ Meson as a QGP Probe
ą is the lightest bound state of hidden strangeness whose production is suppressed by OZI rule in pp and Ĉp collisions. In QGP scenario, ą can be easily produced by s and s quarks coalescence during hadronization stage.
That ąN and ąĈ re-scattering cross section is small (~1mb) makes ą to be a penetrating probe of a decaying QGP.
The mass and width of vector mesons is demonstrated theoretically sensitive the temperature and baryon density of nuclear medium in heavy-ion collisions.
