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 ...
