More about the B and D mesons in nuclear matter
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 ...
Thermal properties of the heavy axial vector quarkonia
(Institute of Atomic Physics, 2014)
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 ...
Strong ΛbNB and ΛcND vertices
(American Physical Society, 2014-12-04)
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 ...
Semileptonic transition of tensor chi(c2)(1P) to D-S meson
(Hindawi Publishing Corporation, 2014)
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 ...
Thermal properties of D-2* (2460) and D-s2*(2573) tensor mesons using QCD sum rules
(IOP Publishing, 2014-03)
We investigate the masses and decay constants of the heavy-lightD(2)* (2460) and D-s2*(2573) tensor mesons in the framework of thermal QCD sum rules. Taking into account the additional operators arising at finite temperature, ...
Analysis of the strong D-2* (2460)(0) -> D+ pi(-) and D-s2*(2573)(+) -> D+ K-0 transitions via QCD sum rules
The strong D-2* (2460)(0) -> D+ pi(-) and D-s2* (2573)(+) -> D+ K-0 transitions are analyzed via three-point QCD sum rules. First we calculate the corresponding strong coupling constants g(D2)*D pi and g(Ds2)*DK. Then we ...
