#### Analysis of the strong D-2* (2460)(0) -> D+ pi(-) and D-s2*(2573)(+) -> D+ K-0 transitions via QCD sum rules

(Springer, 2014-10-21)

The strong D-2* (2460)(0) -> D+ pi(-) and D-s2* (2573)(+) -> D+ K-0 transitions are analyzed via three-point QCD sum rules. First we calculate the corresponding strong coupling constants g(D2)*D pi and g(Ds2)*DK. Then we ...

#### On the strong coupling N(*)N(*)pi

(Springer, 2016-04-26)

We study the strong vertices N*N pi, N*N*pi and NN pi in QCD, where N* denotes the negative-parity N(1535) state. We use the most general form of the interpolating currents to calculate the corresponding strong coupling ...

#### Mass and magnetic dipole moment of negative-parity heavy baryons with spin-3/2

(Springer, 2017-01-18)

We calculate the mass and residue of the heavy spin-3/2 negative-parity baryons with single heavy bottom or charm quark by use of a two-point correlation function. We use the obtained results to investigate the diagonal ...

#### 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 P-c(+)(4380) and P-c(+)(4450) as pentaquark states in the molecular picture with QCD sum rules

(American Physical Society, 2017-05-24)

To better understand the nature and internal structure of the exotic states discovered by many collaborations, more information on their electromagnetic properties and their strong and weak interactions with other hadrons ...

#### Hidden bottom pentaquark states with spin 3/2 and 5/2

(American Physical Society, 2017-11)

Theoretical investigations of the pentaquark states that were recently discovered provide important information on their nature and structure. It is necessary to study the spectroscopic parameters, like masses and residues ...

#### New a(1)(1420) state: structure, mass, and width

(American Physical Society, 2018-03)

The structure, spectroscopic parameters and width of the resonance with quantum numbers J(PC) = 1(++) discovered by the COMPASS Collaboration and classified as the a(1)(1420) meson are examined in the context of QCD sum ...

#### Strong decay of P-c (4380) pentaquark in a molecular picture

(Elsevier, 2018-07-10)

There are different assumptions on the substructure of the pentaquarks P-c(4380) and P-c(4450), newly founded in J/psi N invariant mass by the LHCb Collaboration, giving consistent mass results with the experimental ...
