Light D-wave axial-tensor K2(1820) meson at finite temperature
(IOP Publishing, 2019-06)
In this work the properties of the axial-tensor K-2(1820) meson in a hot medium are investigated. The mass and the decay constant of this state are calculated via thermal QCD sum rules considering QCD condensates up to ...
Exploratory study of χc1(4140) and like states in QCD sum rules
(Elsevier, 2019-05)
In this work, we chose three molecular and three diquark-antidiquark currents with the quark content c (c) over bars (s) over bar and J(PC) = 0(++), 1(++), 2(++), and estimated the masses and the meson coupling constants ...
In the pursuit of X(5568) and its charmed partner
(Jagellonian University, 2019-09)
The recent observation by the D empty set Collaboration of the first tetraquark candidate with four different quark flavors (u, d, s and b) in the B-s(0)pi(+/-) channel having a narrow structure has still not been confirmed ...
Hot medium effects on pseudotensor K2(1820) meson
(EDP Sciences, 2019)
The investigation of mesons in hot medium can give valuable information about the nature of QCD vacuum and deconfinement phase transitions. In this study, thermal properties of pseudotensor K-2(1820) meson is examined via ...
Investigation of the excited states in hidden charm hidden strange sector
(2018)
In this work, we studied the radial excitations of X(4140) and like states within QCD sum rules. We chose three molecular and three diquark-antidiquark currents with the quark content cc‾ss‾ and JPC = 0++, 1++, 2++, and ...
Hidden-beauty broad resonance Yb(10890) in thermal QCD
(Hindawi Limited, 2019)
In this work, the mass and pole residue of resonance Yb is studied by using QCD sum rules approach at finite temperature. Resonance Yb is described by a diquark-antidiquark tetraquark current, and contributions to operator ...
Mass and pole residue of Yb(10890) state with JPC = 1−− at finite temperature
(AIP Publishing, 2019)
The status of the hidden beauty state Y-b is not clear up to now. The deviations from the expected behavior can provide a clue to consider it as an exotic meson candidate. Assuming the Y-b resonance as a tetraquark, we ...
S-wave single heavy baryons with spin-3/2 at finite temperature
(Springer Nature, 2020-05-15)
The thermal behavior of the spectroscopic parameters of the S-wave single heavy baryons Sigma Q,Xi Q and Omega Q with spin-3/2 are investigated in QCD at finite temperature. We analyze the variations of the mass and residue ...
Investigating the structure of X(4140) in QCD
(EDP Sciences, 2017)
In this work, the masses of the ground states coupling to molecular or tetraquark currents with JPC = 0++, 1++, 2++ are studied to investigate the structure of X(4140) exotic meson observed at J/ψφ invariant mass spectrum. ...
Properties of spin-1=2 heavy baryons at nonzero temperature
(American Physical Society, 2021-11-18)
The spectroscopic properties of single heavy spin-1/2 ΛQ, ςQ, ΞQ(′), and ωQ baryons are investigated at finite temperature in the framework of the thermal QCD sum rule. We discuss the behavior of the mass and residue of ...
