Light cone QCD sum rules study of the semileptonic heavy Xi(Q) and Xi(Q)' transitions to Xi and Sigma baryons
The semileptonic decays of heavy spin-1/2, Xi(b(c)) and Xi(b(c))' baryons to the light spin-1/2, Xi and S baryons are investigated in the framework of light cone QCD sum rules. In particular, using the most general form ...
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 ...
Thermal behaviors of light unflavored tensor mesons in the framework of QCD sum rule
(IOP Publishing, 2014)
In this paper, we investigated the sensitivity of the masses and decay constants of f(2)(1270) and a(2)(1320) tensor mesons to the temperature using OCD sum rule approach. In our calculations, we take into account new ...
Analysis of the semileptonic transition of heavy Xi(Q) baryon to Xi baryon in Light Cone QCD Sum Rules
This study presents the analysis of form factor calculations of semileptonic transitions of heavy baryons via light cone QCD sum rules. The work covers the semileptonic transitions of the Xi(b) and Xi(c) baryons. The form ...
Strong Z(c)(+)(3900) -> J/psi pi(+); eta c rho(+)decays in QCD
(American Physical Society, 2016-04-01)
The widths of the strong decaysZ(c)(+)(3900) -> J/psi pi(+); and Z(c)(+) (3900) -> are calculated. To this end, the mass and decay constant of the exotic Z(c)(+) (3900) state are computed by means of a two -point sum rule. ...
