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 ...
Theoretical determination of K(1)(1270,1400) mixing angle in QCD
(IOP Publishing, 2012)
In quark model, the strange axial vector mesons K1(1270) and K1(1400) are defined as the mixtures of orbital angular momentum states K1A and K1B. In this work, by using the orthogonality of the mass eigenstates, we have ...
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. ...
