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.

The effect of the vacuum asymmetry [Formula: see text] on π0pp and π0nn coupling constants has been estimated in the QCD sum rules approach. This effect can contribute to charge symmetry breaking in nuclear forces (CSB). The experimental information on CSB is used to estimate εd and the other vacuum asymmetry. [Formula: see text]. It is shown that the values of εs larger than 0.3 still allowed by QCD sum rules in light baryon and meson sectors are not possible.
