#### Semileptonic Lambda b,c to nucleon transitions in full QCD at light cone

(American Physical Society, 2009-11)

The tree-level semileptonic Lambda(b)-> pl nu and Lambda(c)-> nl nu transitions are investigated using the light cone QCD sum rules approach in full theory. The spin 1/2, Lambda(Q) baryon with Q=b or c, is considered by ...

#### FCNC transitions of Lambda(b,c) to nucleon in SM

(IOP Publishing, 2010-11)

We provide a comprehensive study of semileptonic flavor-changing neutral current transitions for Lambda(b) -> nl(+) l(-) and Lambda(c) -> pl(+) l(-) in the context of light cone QCD sum rules. Using the most general form ...

#### Semileptonic bs -> ds2*(2573) l(nu)over-barl transition in QCD

(Springer, 2015-05-06)

We analyze the semileptonic B-s -> D-s2*(2573) l (nu) over bar (l) transition, where l = tau, mu or e, within the standard model. We apply the QCD sum rule approach to calculate the transition form factors entering the low ...

#### Radiative transition of negative to positive parity nucleon

(American Physical Society, 2015-05-27)

We investigate the N*(1535) -> N gamma transition in the framework of light cone QCD sum rules. In particular, using the most general form of the interpolating current for the nucleon as well as the distribution amplitudes ...

#### Radiative omega(Q)* -> omega(Q)gamma and qi(Q)* -> xi(Q)'gamma transitions in light cone QCD

(Springer, 2015-01-14)

We calculate the magnetic dipole and electric quadrupole moments associated with the radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions with Q = b or c in the framework of light cone QCD sum rules. ...

#### 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. ...

#### Transition form factors of chi(b2)(1P) -> B-c(l)over-barv in QCD

(Hindawi, 2016)

The form factors of the semileptonic chi(b2)(1P) -> B-c(l) over barv decay are calculated by using the QCD sum rule technique. The results obtained are then used to estimate the decay widths of this transition in all lepton ...

#### Analysis of the structure of Xi (1690) through its decays

(Springer, 2018-05)

The mass and pole residue of the first orbitally and radially excited Xi state as well as the ground state residue are calculated by means of the two-point QCD sum rules. Using the obtained results for the spectroscopic ...
