#### Impact of finite density on spectroscopic parameters of decuplet baryons

(American Physical Society, 2016-12)

The decuplet baryons, Δ, Σ∗, Ξ∗, and Ω-, are studied in nuclear matter by using the in-medium QCD sum rules. By fixing the three-momentum of the particles under consideration at the rest frame of the medium, the negative ...

#### Exploring X(5568) as a meson molecule

(Springer Verlag, 2016-10)

The parameters, i.e. the mass and current coupling of the exotic X(5568) state observed by the D0 Collaboration as well as the decay width of the process X→B0sπ+X→Bs0π+ , are explored using the BK¯¯¯¯¯BK¯ molecule ...

#### Width of the exotic Xb (5568) state through its strong decay to Bs0 π+

(American Physical Society, 2016-06)

The width of the newly observed exotic state Xb(5568) is calculated via its dominant strong decay to Bs0π+ using the QCD sum rule method on the light cone in conjunction with the soft-meson approximation. To this end, the ...

#### Decay constants of the charmed tensor mesons at finite temperature

(American Institute of Physics, 2016-01)

Investigation of the thermal properties of the mesons with higher spin is one of the important problems in the hadron physics. At finite temperature, the Lorentz invariance is broken by the choice of a preferred frame of ...

#### 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 = ...

#### Charmed partner of the exotic X(5568) state and its properties

(American Physical Society, 2016-05-06)

The mass, decay constant, and width of a hypothetical charmed partner X-c of the newly observed exotic X-b(5568) state are calculated using the technique of the QCD sum rule method. The X-c = [su][(c) over bar(d) over bar] ...

#### Mass and decay constant of the newly observed exotic X(5568) state

(American Physical Society, 2016-04-20)

The mass and decay constant of the X(5568) state newly observed by the D0 Collaboration are computed within the two-point sum rule method using the diquark-antidiquark interpolating current. In calculations, the vacuum ...

#### 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. ...

#### 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 ...

#### 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 ...
