Detail description
Υ(1S) and Y(2S) yields dN(1S) /dy, dN(2S) /dy at forward-rapidity (Υ(1S), Y(2S) →mu+mu−, 2.5 < y <4.0) 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 (dN(1S)/dy, dNch/dη) and (dN(2S) /dy, dNch/dη). The error bars represent the statistical uncertainty, while the point-by-point systematic uncertainties on the ratio of relative Υ(1S) and relative Y(2S) yields as a function of charged particle multiplicity is depicted as boxes. The dotted linear line is drawn to y=1.
