Detecting h_c(^1P_1) at the LHC

Abstract

In this work, we calculate the $h_c{(}^1{P}_1)$ production rate at the LHC to leading order of the strong coupling constant, for both color-singlet and -octet mechanisms. Numerical results show that a considerable number of $h_c$ events with moderate transverse momentum $p_T$ will be produced in the early run of the LHC, which will supply a good opportunity to further study the nature of this P-wave spin-singlet charmonium state.
