Measurement of the relative cross-section $\sigma(\chi_{c_2})/\sigma(\chi_{c_1})$ of prompt $\chi_c$ mesons using at LHCb
The production of heavy quarkonia remains a challenging problem for understanding Quantum Chromodynamics (QCD). This note reports on the production cross-section ratio of $\sigma(\chi_{c2})/\sigma(\chi_{c1})$ with the $\chi_c$ state decaying into $\chi_c \rightarrow J/\psi \gamma$. The $J\psi$ is i...
