Investigating charmonium production at LHC with the p pbar final state

TL;DR

This paper proposes studying charmonium production at the LHC via the p pbar decay channel to enhance understanding of QCD processes and measure previously unobserved states like eta_c and h_c.

Contribution

It introduces a method to measure various charmonium production rates through their p pbar decay channel at LHC, including unmeasured states, with implications for QCD.

Findings

Potential to measure eta_c and h_c production rates.

Insights into soft-diffraction and b-hadron decay contributions.

Impacts on theoretical QCD models.

Abstract

We propose to investigate various charmonium states using their common decay channel to p pbar at LHC. Having the branching ratios for charmonium decaying into the p pbar final state measured or calculated, we propose to measure the charmonium production rate for both hadroproduction including soft-diffraction and inclusive production from b-hadron decays. We discuss the theoretical impacts in QCD of measuring different charmonium production rates and also the experimental prospects at LHCb, in particular, those for yet unmeasured eta_c and h_c.
