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 ...
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 ...
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 ...
