Semileptonic transition of P-wave bottomonium chi(b0)(1P) to B-c meson
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 ...
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.
Doubly heavy spin-1/2 baryon spectrum in QCD
We calculate the mass and residue of the heavy spin-1/2 baryons containing two heavy h or c quarks in the framework of QCD sum rules. We use the most general form of the interpolating current in its symmetric and anti-symmetric ...
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 ...
Electromagnetic form factors of octet baryons in QCD
The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic ...
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 ...
Exploring the electromagnetic form factors of the scalar K-0(*)(1430), f(0)(1500) and a(0)(1450) mesons in light-cone sum rules
(American Physical Society, 2013-05-28)
We calculate the electromagnetic form factors of the scalar K-0(*)(1430), f(0)(1500) and a(0)(1450) mesons by considering them as regular quark-antiquark states and using their distribution amplitudes within the light-cone ...
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 ...
The masses and residues of doubly heavy spin-3/2 baryons
(IOP Publishing, 2013-06)
The masses and residues of the spin-3/2 doubly heavy baryons are calculated within the QCD sum rules method. A comparison of our predictions with those existing in the literature is also made.
