Abstract

The mass and decay constant of the heavy quarkonia h_Q(1P) and h_Q(2P) (Q = b, c) with quantum numbers J^PC =1^+- are calculated in the framework of the two-point QCD sum rule method by taking into account the vacuum condensates up to eight dimensions. We compare our results for parameters of the h_b(1P) and h_c(1P) quarkonia, and their first radially excited states h_b(2P) and h_c(2P) with available experimental data as well as predictions of other theoretical studies existing in the literature. The results of present work may shed light on experimental searches for the h_c(2P) state.
