Experimental Aspects of Heavy Quarkonium Production at the LHC

More than 30 years after the discovery of the J/psi, its production mechanism is still poorly understood. With the LHC data it will be possible to study quarkonia up to very high transverse momenta and with high statistics. In this note we discuss experimental aspects of J/psi and Upsilon(1S) production at the LHC. In particular, we investigate the sensitivity of a general purpose LHC detector to observables, which are complementary to the cross section and polarisation measurement. These observables would be sensitive to the radiation produced in association with the quarkonium.
