Query: J/{\Psi} and {\Psi}(2S) Production in p-Pb Collisions at 5.02 TeV with
  ATLAS   The production rates of heavy quarkonia in ion-ion collisions provide
sensitive probes in the studies of the hot and dense matter formed in these
collisions at high energies. However, a reference for understanding the
behavior in the hot medium is necessary; p-A collisions open the possibility to
study heavy quarkonia states in a smaller system of much lower average
temperature. This is an important step in forming a baseline for understanding
A-A collisions, as well as an investigation into the nature of modifications of
the parton distributions in the nucleus. Using data collected at the LHC in
2013, we show results on the prompt J/{\Psi} and {\Psi}(2S) nuclear
modification factors and the double ratio, {\Psi}(2S) divided by J/{\Psi} in
p-Pb divided by the same in p-p, in p-Pb collisions at 5.02 TeV. The charmonia
states were reconstructed via the dimuon decay channel and the yield is
analyzed differentially in bins of transverse momentum, rapidity, and event
activity.
