Lh_c

TL;DR

This paper predicts a large production cross-section for the h_c charmonium state at the LHC using NRQCD, suggesting it can be observed via its decay into J/psi + pi within a few months of data collection.

Contribution

It demonstrates the feasibility of detecting the h_c state at the LHC through its decay channel, based on theoretical cross-section predictions using heavy-quark symmetry in NRQCD.

Findings

Large cross-section predicted for h_c at LHC

Potential observation of h_c within months of data collection

Supports experimental search strategies for charmonium states

Abstract

The production cross-section of h_c, the 1P_1 charmonium state, can be predicted in Non-Relativistic QCD (NRQCD) using heavy-quark symmetry. We show that at the Large Hadron Collider a large cross-section for this resonance is predicted and it should be possible to look for the h_c through it decay into J/psi +pi even with the statistics that will be achieved within a few months of run-time at the LHC.
