The comparison of relative J/$\psi$ yield at forward rapidity ( $ -4.0 < \it{y} < -2.5 $ )  as a function of relative charged-particle densities  at mid-rapidity in pp collisions  at $\sqrt{s} = 5.02 TeV$ with $\sqrt{s} = 13 TeV$  and at  mid-rapidity  ( $ | \it{y} | < 0.9 $ )  in pp $\sqrt{s} = 13 TeV$ for $ INEL > 0 $ event class.

Detail description

The comparison of relative J/$\psi$ yield at forward rapidity ( $ -4.0 < \it{y} < -2.5 $ )  as a function of relative charged-particle densities  at mid-rapidity in pp collisions  at $\sqrt{s} = 5.02 TeV$ with $\sqrt{s} = 13 TeV$  and at  mid-rapidity  ( $ | \it{y} | < 0.9 $ )  in pp $\sqrt{s} = 13 TeV$ for $ INEL > 0 $ event class.  is shown. Self normalisation is done by respective integrated values of inclusive  J/$\Psi$ yield and integrated  $<dN_{ch}/d\eta >$ for event class inelastic >0 ( $INEL>0 $) in both energies. The vertical error bars represents statistical uncertainties while the light blue boxes show the systematics uncertainties. The black dotted line is a linear function ( y=x ) describes the behaviour of the  J/$\psi$ yield with multiplicity multiplicity dependence.
