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 ...
