$J/\psi$ production in pp collisions at $\sqrt{{\rm s}}$=200GeV in the   STAR experiment
  In this work we present the $J/\psi$ measurement in p+p collisions within the STAR collaboration Quarkonium program. This measurements aim to be the baseline measurement of a more comprehensive systematic study of quarkonium states production in order to understand their in medium modification. Here we report the total cross section and $p_T$ distribution, and find them to be consistent with pQCD CEM predictions as well as to previous measurements at the same center-of-mass energy.
