We calculate the mass and residue of the nucleon in nuclear matter in the frame work of QCD sum rules using the nucleon's interpolating current with an arbitrary mixing parameter. We evaluate the effects of the nuclear ...

We calculate the shifts in decay constants of the pseudoscalar B and D mesons in nuclear medium in the frame work of QCD sum rules. We write those shifts in terms of the B-N and D-N scattering lengths and an extra ...

The strong coupling constants, gD(s)DK(0)*, gB(s)BK(0)*, gD(s)*DK, gB(s)*BK, gD(s)*DK1 and gB(s)*BK(1), where K(0)*, K and K(1) are scalar, pseudoscalar, and axial-vector kaon mesons, respectively, are calculated in the ...

The mass and current coupling constant of the D-s2*(2573) charmed-strange meson is calculated in the framework of the two-point QCD sum rule approach. Although the quantum numbers of this meson are not exactly known, its ...

We calculate the mass and meson-current coupling constant of the D-2*(2460) tensor meson in the framework of QCD sum rules. The obtained result on the mass is compatible with the experimental data.

Using the additional operators coming up at finite temperature, we calculate the masses and decay constants of the P wave heavy axial-vector chi(b1) and chi(c1) quarkonia in the framework of thermal QCD sum rules. In the ...

We investigate the strong vertices among the Lambda(b), nucleon, and B meson as well as the Lambda(c), nucleon, and D meson in QCD. In particular, we calculate the strong coupling constants g Lambda bNB and g Lambda cND ...

Taking into account the two-gluon condensate contributions, the transition form factors enrolled to the low-energy effective Hamiltonian describing the semileptonic chi(b0) -> B(c)l (nu) over bar, (l = (e, mu, tau)) decay ...

Taking into account the two-gluon condensate corrections, the transition form factors of the semileptonic chi(c2) -> D-s(l) over bar nu(l - e, mu) decay channel are calculated via three-point QCD sum rules. These form ...

Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers I-G (J(PC)) = 0(+)(0(++)), are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The ...
