In this work we shall investigate the mass modifications of scalar mesons (D0;B0), vector mesons (D*;B*), and axial-vector mesons (D1;B1) at finite density and temperature of the nuclear medium. The above mesons are modified in the nuclear medium through the modification of quark and gluon condensates. We will find the medium modification of quark and gluon condensates within chiral SU(3) model through the medium modification of scalar-isoscalar fieldsσandζat finite density and temperature. These medium modified quark and gluon condensates will further be used through QCD sum rules for the evaluation of in-medium properties of the above mentioned scalar, vector, and axial vector mesons. We will also discuss the effects of density and temperature of the nuclear medium on the scattering lengths of the above scalar, vector, and axial-vector mesons. The study of the medium modifications of the above mesons may be helpful for understanding their production rates in heavy-ion collision experiments. The results of present investigations of medium modifications of scalar, vector, and axial-vector mesons at finite density and temperature can be verified in the compressed baryonic matter (CBM) experiment of FAIR facility at GSI, Germany.

In this paper, we calculate the mass modifications of the vector and axial vector mesons D*, B*, D1 and B1 in the nuclear matter with the QCD sum rules, and obtain the mass-shifts δMD* = -71 MeV , δMB* = -380 MeV , δMD1 = 72 MeV , δMB1 = 264 MeV , and the scattering lengths aD* = -1.07 fm , aB* = -7.17 fm , aD1 = 1.15 fm and aB1 = 5.03 fm for the D*N, B*N, D1N and B1N interactions, respectively.
