Fate of the doubly heavy spin3/2 baryons in a dense medium
(American Physical Society, 2019)We investigate the behavior of the doubly heavy spin3/2 baryons in cold nuclear matter. In particular, we study the variations of the spectroscopic parameters of the ground state Xi(QQ')* and Omega(QQ')* particles, with ... 
Determination of the quantum numbers of Σb (6097) (+/) via their strong decays
(American Physical Society, 2019)Recent experimental progress has led to the detection of many new hadrons. Very recently, the LHCb Collaboration announced the observation of two new Sigma(b)(6097)(+/) states in the Lambda(0)(b)pi(+/) invariant mass ... 
Corrigendum to “Scalar and vector selfenergies ofheavy baryons in nuclear medium”
(Elsevier, 2017)In this erratum, we correct some misprints in equation (13) of our paper Nucl. Phys. A 960 (2017) 147–164. The corrected form of this equation is:[Formula presented] As they are only misprints and their correct forms have ... 
Strong decays of doublecharmed pseudoscalar and scalar cc(u)overbar(d)overbar tetraquarks
(American Physical Society, 2019)The strong decays of the pseudoscalar and scalar doublecharmed tetraquarks Tþ cc; ¯ud¯ and T˜ þ cc; ¯ud¯ are investigated in the framework of the QCD sum rule method. The mass and coupling of these exotic fourquark mesons ...

(Springer, 201903)The mass, coupling and width of the newly observed charged resonance Z−c(4100) are calculated by treating it as a scalar fourquark system with a diquark–antidiquark structure. The mass and coupling of the state ... 
Weak decays of the axialvector tetraquark Tbb;(u)overbar(d)overbar()
(American Physical Society, 201902)The weak decays of the axialvector tetraquark Tbb;(u) over bar(d) over bar() to the scalar state Z(bc;(u) over bar(d) over bar)(0) are investigated using the QCD threepoint sum rule approach. In order to explore the ...

Interpretation of the newly discovered Ω (2012)
(American Physical Society, 2018)Very recently, Belle Collaboration reported observation of a narrow state called Ω(2012) with mass 2012.4±0.7(stat)±0.6(syst) MeV and width 6.42.0+2.5(stat)±1.6(syst) MeV. We calculate the mass and residue of the Ω(2012) ...

(Elsevier, 201806)The mixing angle, mass and couplings of the light scalar mesons f0(500) and f0(980) are calculated in the framework of QCD twopoint sum rule approach by assuming that they are tetraquarks with diquark–antidiquark structures. ... 
Strong decay of Pc(4380) pentaquark in a molecular picture
(Elsevier, 201807)There are different assumptions on the substructure of the pentaquarks Pc(4380) and Pc(4450), newly founded in J/ψN invariant mass by the LHCb Collaboration, giving consistent mass results with the experimental observations. ...
