Top Panel:

J/ψ yield dNJ/ψ /dy at forward-rapidity (J/ψ →mu+mu−, 2.5 < y <4.0) and mid-rapidity(J/ψ →e+e−, |y| <1.0) are compared as a function of charged-particle multiplicity densities at mid-rapidity dNch/dη for pp collisions at \sqrt{s} = 13 TeV. Both values are normalized by the corresponding value for minimum bias pp collisions (dNJ/ψ /dy, dNch/dη). The error bars represent the statistical uncertainty on the J/ψ yields, while the point-by-point systematic uncertainties on the J/ψ yield is depicted as boxes. The dotted linear line (y=x) is drawn to see the deviation from non-linearity of the points.

 

Bottom panel:

The ratio of relative yield of J/ψ to relative yield of charged-particle multiplicity.
