Open charm meson in finite temperature nuclear matter

In mid-May last year, I presented an informal seminar to McGill Nuclear theorists/experimentalists on the properties of open charm mesons (D) in cold (T=0) nuclear matter. The model exploited a self-consistent coupled-channel approach, equipped with a broken SU(4) s-wave Tomozawa-Weinberg meson-baryon interaction, supplemented by a scalar-isoscalar attraction. One of the questions at that occasion was on the effect of finite temperature. I had a temporary answer, but since it was not supported by an actual calculation, I responded as “I have no idea”, to be on the safe side. An extention including finite temperature, mean nuclear field binding on all the baryons in the coupled channels, etc. has been performed recently. The result of the calculation will be reported, in its relevance to speculating the possibility of D-mesic nuclei, as well as to the J/Ψ suppression in relativistic (but not Ultra!) heavy-ion collisions, in particular for the future CBM experiment at FAIR (GSI).
