Query: Event patterns extracted from transverse momentum and rapidity spectra
  of Z bosons and quarkonium states produced in pp and Pb-Pb collisions at LHC   Transverse momentum ($p_T$) and rapidity ($y$) spectra of $Z$ bosons and
quarkonium states (some charmonium $c\bar c$ mesons such as $J/\psi$ and
$\psi(2S)$, and some bottomonium $b\bar b$ mesons such as $\Upsilon(1S)$,
$\Upsilon(2S)$, and $\Upsilon(3S)$) 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 $p_T$
spectrum and two-component Gaussian distribution for $y$ 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 $\sqrt{s}=2.76$ and 7 TeV, and in Pb-Pb collisions at
center-of-mass energy per nucleon pair $\sqrt{s_{NN}}=2.76$ TeV. Based on the
parameter values extracted from $p_T$ and $y$ spectra, the event patterns
(particle scatter plots) in two-dimensional $p_T$-$y$ space and in
three-dimensional velocity space are obtained.
