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 ...
Strong Ds∗ Dsη (′) and Bs∗ Bsη (′) vertices from QCD light-cone sum rules
(American Physical Society, 2015-12-29)
The strong Ds∗Dsη(′) and Bs∗Bsη(′) vertices are studied and the relevant couplings are calculated in the context of the light-cone QCD sum rule method with twist-4 accuracy by including the next-to-leading-order corrections. ...
Strong couplings of negative and positive parity nucleons to the heavy baryons and mesons
(American Physical Society, 2015-07-20)
The strong coupling form factors related to the strong vertices of the positive and negative parity nucleons with the heavy Lambda(b[c])[Sigma b[c]] baryons and heavy B*[D*] vector mesons are calculated using a threepoint ...
Scalar and vector self-energies of heavy baryons in nuclear medium
The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the calar and vector self-energies of the heavy Lambda(Q), Sigma(Q) and Xi(Q) baryons, with Q being b or c quark. The maximum ...
