#### Properties of nucleon in nuclear matter: once more

(Springer, 2014-05-27)

We calculate the mass and residue of the nucleon in nuclear matter in the frame work of QCD sum rules using the nucleon's interpolating current with an arbitrary mixing parameter. We evaluate the effects of the nuclear ...

#### Magnetic moments of Xi '(Q)-Xi(Q) transitions in light cone QCD

(American Physical Society, 2014-03-11)

The Xi '(Q)-Xi(Q) transition magnetic moments are calculated in a framework of the light cone QCD sum rules method. The values of the transition magnetic moments obtained are compared with the predictions of the other ...

#### 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 ...

#### G(Sigma Q Sigma Q pi) coupling constant via light cone QCD sum rules

(American Physical Society, 2010-10-11)

Using the most general form of the interpolating currents, the coupling constants g(Sigma b Sigma b pi) and g(Sigma c Sigma c pi) are calculated within the light cone QCD sum rules approach. It is found that g(Sigma c Sigma ...

#### 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 ...

#### 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 ...

#### Application of the QCD light cone sum rule to tetraquarks: The strong vertices XbXb rho and XcXc rho

(American Physical Society, 2016-06-30)

The full version of the QCD light-cone sum rule method is applied to tetraquarks containing a single heavy b or c quark. To this end, investigations of the strong vertices XbXb rho and XcXc rho are performed, where X-b = ...

#### 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. ...

#### Magnetic and quadrupole moments of the Z(c)(3900)

(American Physical Society, 2017-10)

The electromagnetic properties of the tetraquark state Z(c)(3900) are investigated in the diquark-antidiquark picture and its magnetic and quadrupole moments are extracted. To this end, the light-cone QCD sum rule in ...
