Bottomonium Production at the Tevatron and the LHC

Abstract

Inclusive bottomonium hadroproduction at the Tevatron is firstly examined in a Monte Carlo framework with the colour-octet mechanism implemented in the event generation. We extract some NRQCD colour-octet matrix elements relevant for ${\rm Y}(1S)$ hadroproduction. Remarkably we find a quite small contribution (compatible with zero) from feeddown of ${\chi }_{bJ}$ states produced through the colour-octet mechanism: ${\rm Y}(1S)$ indirect production via ${\chi }_{bJ}$ decays should be mainly ascribed to the colour-singlet model. Finally we extrapolate to LHC energies to predict prompt ${\rm Y}(1S)$ production rates.
