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 ...
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 ...
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 ...
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. ...
Dissociation of pseudotensor mesons π2(1670), η2(1645) and η2(1870) through critical temperature
(Springer, 2022-09-27)
We have computed the masses and decay constants of isotriplet π2(1670), the isoscalar η2(1645) and η2(1870) states as the ground-state nonet of 1 1D2 case within the Thermal QCD sum rules framework. This method is applied ...
Properties of kaon at non-zero temperature and baryon chemical potential
(Springer, 2023-10-14)
We investigate the spectroscopic properties of the strange particle kaon in the framework of hot and dense QCD. To this end, first, we find the perturbative spectral density, which is connected with both the temperature T ...
Melting of 𝜌2 meson at extreme temperatures
(American Institute of Physics Inc., 2019)
The thermal properties of the light tensor ρ2 meson with quantum numbers JPC = 2- are studied at finite temperature. In our calculations, two-point Thermal QCD sum rules approach is employed including contributions up to ...
