Properties of nucleon in nuclear matter: once more
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 ...
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 ...
Radiative Σb→Σγ decay in SM and BSM
(IOP Publishing, 2014-09)
Using transition form factors calculated via light cone QCD sum rules in full theory, we comparatively analyze the rare radiative Sigma(b) -> Sigma gamma decay in the standard model (SM) and models with one or two universal ...
Magnetic moments of Xi '(Q)-Xi(Q) transitions in light cone QCD
(American Physical Society, 2014-03-11)
The Xi '(Q)-Xi(Q) transition magnetic moments are calculated in a framework of the light cone QCD sum rules method. The values of the transition magnetic moments obtained are compared with the predictions of the other ...
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 ...
Properties of triply heavy spin-3/2 baryons
(IOP Publishing, 2014-06)
The masses and residues of the triply heavy spin-3/2 baryons are calculated in framework of the QCD sum rule approach. The obtained results are compared with the existing theoretical predictions in the literature.
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, ...
In-medium properties of b and d mesons
(EDP Sciences, 2014-11-24)
The shifts in the masses and decay constants of B and D mesons in nuclear medium are calculated in the frame work of QCD sum rules. The results obtained are compared with the existing theoretical predictions.
