Measurement of

We present measurements of J/ψ production in the dielectron channel at mid rapidity (|y| <1) over the transverse momentum range 4 < pT < 12 GeV/c examined as a function of the charged-particle multiplicity within |η| < 1. Our measurements reveal a faster-than-linear increase in J/ψ production with respect to charged-particle multiplicity, extending previously reported trends at 200 GeV. The divergence of the trends for RHIC and LHC at higher multiplicity may constrain theoretical models incorporating multi-parton interactions and color-string percolation.
