On the mass and the decay constant of recently observed bound state $h_b(1P)$

Abstract

The mass and decay constant of the ground state of spin singlet $b\bar{b}$ is calculated by using the QCD sum rules method. This meson is an axial vector $P$-wave named $h_b(1P)$ meson with $J^P=1^{+}$. It is found that the mass of this meson is $(m=9940\pm 37)$ MeV, which is consistent with the recent experimental data by Belle collaboration.
