Scalar D₀ and B₀ mesons in hot and dense strange hadronic medium

We observed the medium modification of masses and decay constants of scalar D and B mesons in hot and dense strange medium using chiral SU(3) model and QCD sum rule approach. If D meson get large mass reduction, then higher charmonium states can decay to these mesons instead of J/ψ(cc¯), hence J/⍦ is suppressed. Similarly, γ(bb¯) will be suppressed if B meson undergo large mass reduction in the medium. The understanding of in-medium properties of D and B mesons will be important for experiments, like, CBM (Compressed Baryonic Matter) and PANDA (anti-Proton Annihilation at Darmstadt) under FAIR project at GSI, Germany
