Vertices of the heavy spin-3/2 sextet baryons with light vector mesons in QCD
All transitions among the heavy spin-3/2 sextet baryons with participation of the light vector mesons (B(Q)(not equal)B(Q)V) are investigated in the framework of the light cone sum rules. These vertices are described by ...
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.
Rare radiative Bc -> Ds1(2460)gamma transition in QCD
(American Physical Society, 2013-01-22)
We investigate the radiative B-c -> D-s1 gamma transition in the framework of QCD sum rules. In particular, we calculate the transition form factors responsible for this decay in both weak annihilation and electromagnetic ...
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
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
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. ...
Analysis of the Lambda b -> Lambda l(+)l(-) decay in QCD
(American Physical Society, 2010-03-01)
Taking into account the Lambda baryon distribution amplitudes and the most general form of the interpolating current of the Lambda(b), the semileptonic Lambda(b) --> Lambda l(+)l(-) transition is investigated in the framework ...
B to D(D*)ev(e) transitions at finite temperature in QCD
(American Physical Society, 2010-05-01)
In this article, we work out the properties of the B, D, and D* mesons as well as the B -> D(D*)ev(e) decay properties at finite temperature QCD. The behavior of the masses, decay constants and widths of the B, D, and D* ...
