Abstract
The phenomenology of the production of P-wave χ c,b mesons and S-wave η c,b mesons in highenergy hadron–hadron collisions was studied on the basis of nonrelativistic quantum chromodynamics (NRQCD). Available experimental data on χ c -meson production were analyzed, and nonperturbative NRQCDmatrix elements were determined from a fit to these data. It is shown that the observed transversemomentum (pT) spectrum of χ c mesons is basically formed by color-singlet contributions. At the same time, the ratio σ(χ c2)/σ(χ c1) depends greatly on color-octet contributions; this ratio therefore becomes a highly sensitive tool for separating different NRQCD contributions. Predictions for χ b -meson production are obtained on the basis of NRQCD scaling rules. For the case of η c -meson production, it is shown that the observed cross sections agree with the color-singlet model featuring phenomenological parameters.
