#### Light cone QCD sum rules study of the semileptonic heavy Xi(Q) and Xi(Q)' transitions to Xi and Sigma baryons

(Springer, 2012-01-20)

The semileptonic decays of heavy spin-1/2, Xi(b(c)) and Xi(b(c))' baryons to the light spin-1/2, Xi and S baryons are investigated in the framework of light cone QCD sum rules. In particular, using the most general form ...

#### Spin-3/2 to spin-1/2 heavy baryons and pseudoscalar mesons transitions in QCD

(Springer, 2011-06)

The strong coupling constants of light pseudoscalar mesons with spin-3/2 and spin-1/2 heavy baryons are calculated in the framework of light cone QCD sum rules. It is shown that each class of transitions among members of ...

#### Properties of bound states containing fourth family quarks

(IOP Publishing, 2012)

The heavy fourth generation of quarks that have sufficiently small mixing with the three known SM families form hadrons. In the present work, we calculate the masses and decay constants of mesons containing either both ...

#### Investigation of the D*s2(2573)+D+K0 vertex via QCD sum rules

(IOP Publishing, 2014-12-08)

In this work the D∗s2(2573)+D+K0 vertex is studied and the coupling constant corresponding to the D∗s2(2573)+ D+K0 transition is calculated. The calculation is performed using three point QCD sum rules method and the value ...

#### g DsDK*0 and g BsDK*0 coupling constants in QCD sum rules

(IOP Publishing, 2012)

In the present study, we calculate the strong coupling constants g DsDK* 0(800) and g BsDK* 0(800) within the three-point QCD sum rules approach. We evaluate the correlation function of the considered vertices taking into ...

#### Decay constants of heavy vector mesons at finite temperature

(IOP Publishing, 2012)

This study deals with determination of the decay constants of heavy vector mesons in the framework of the thermal QCD sum rules. We calculate both thermal spectral density and non-perturbative contributions taking into ...

#### Mesons spectral functions at finite temperature

(IOP Publishing, 2012)

We investigate the thermal spectral densities for (pseudo)scalar and vector currents in the framework of the real time formalism when mass of two quarks are different. Such spectral densities are necessary for the ...

#### Thermal modifications of the heavy axial vector mesons properties

(SISSA, 2012)

We investigate the properties of the heavy axial vector χb1 and χc1 quarkonia at finite temperature. Taking into account the thermal spectral density as well as additional operators coming up at finite temperature and ...

#### Analysis of Ds*DK1 (Bs*BK1) coupling constants within QCD sum rules

(IOP Publishing, 2012)

We compute the strong coupling constants for D*sDK1 and B*sBK1 vertices within the QCD sum rules. The coupling constants are calculated for both D(B) and K1 off-shell mesons.

#### 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 ...
