• Nuclear matter
• QCD sum rules

In this paper, we calculate the mass modifications of the vector and axial vector mesons D*, B*, D-1 and B-1 in the nuclear matter with the QCD sum rules, and obtain the mass-shifts delta M-D* = -71 MeV, delta M-B* = -380 MeV, delta M-D1 = 72 MeV, delta M-B1 = 264 MeV, and the scattering lengths a(D*) = -1.07 fm, a(B*) = -7.17 fm, a(D1) = 1.15 fm and a(B1) = 5.03 fm for the D* N, B* N, D1N and B1N interactions, respectively.
