摘要：Transverse momentum () and rapidity () spectra of bosons and quarkonium states (some charmonium mesons such as and and some bottomonium mesons such as , , and ) produced in proton-proton (pp) and lead-lead (Pb-Pb) collisions at the large hadron collider (LHC) are uniformly described by a hybrid model of two-component Erlang distribution for spectrum and two-component Gaussian distribution for spectrum. The former distribution results from a multisource thermal model, and the latter one results from the revised Landau hydrodynamic model. The modelling results are in agreement with the experimental data measured in pp collisions at center-of-mass energies and 7 TeV and in Pb-Pb collisions at center-of-mass energy per nucleon pair TeV. Based on the parameter values extracted from and spectra, the event patterns (particle scatter plots) in two-dimensional - space and in three-dimensional velocity space are obtained.
