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 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.
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, ...
Properties of D - 2 * (2460) tensor meson and semileptonic transition of B -> D - 2 * (2460) l(v)over - bar
We employ QCD sum rules to calculate the leptonic decay constant of the D-2*(2460) tensor meson and the transition form factors of the semileptonic B -> D-2*(2460)l (v) over bar (l = tau,mu,e) decay channel. Using the fit ...
Heavy baryon-light vector meson couplings in QCD
The strong coupling constants of heavy baryons with light vector mesons are calculated in the framework of the light cone QCD sum rules using the most general form of the interpolating currents for the heavy baryons. It ...
Strong coupling constants of light pseudoscalar mesons with heavy baryons in QCD
We calculate the strong coupling constants of light pseudoscalar mesons with heavy baryons within the light cone QCD sum rules method. It is shown that sextet-sextet, sextet-antitriplet and antitriplet-antitriplet transitions ...
Strong transitions of decuplet to octet baryons and pseudoscalar mesons
The strong coupling constants of light pseudoscalar pi, K and eta mesons with decuplet-oclet baryons are studied within light cone QCD sum rules, where SU(3)(f) symmetry breaking effects are taken into account It is shown ...
Heavy chi(Q) (2) tensor mesons in QCD
The masses and decay constants of the ground state heavy chi(Q2) (Q = b, c) tensor mesons are calculated in the framework of the QCD sum rules approach. The obtained results on the masses are in good consistency with the ...
Properties of bound states containing fourth family quarks
(IOP Publishing, 2012)
The heavy fourth generation of quarks that have sufficiently small mixing with the three known SM families form hadrons. In the present work, we calculate the masses and decay constants of mesons containing either both ...
Analyses of gD*sDK and gB*sBK vertices in QCD sum rules
(IOP Publishing, 2012)
The coupling constants g D*sDK and g B*sBK are calculated in the framework of QCD sum rules. We evaluate the correlation functions of these vertices considering both D(B) and K mesons off-shell and obtain the results as g ...
