【 摘 要 】

Theoretical studies of quarkonia can elucidate some of the important properties of the quark gluon plasma, the state of matter realised when the temperature exceeds O(150) MeV, currently probed by heavy-ion collisions experiments at BNL and the LHC. We report on our results of lattice studies of bottomonia for temperatures in the range 100MeV T 450 MeV, introducing and discussing the methodologies we have applied. Of particular interest is the analysis of the spectral functions, where Bayesian methods borrowed and adapted from nuclear and condensed matter physics have proven very successful.
