Figure 11

Transverse momentum dependence of the inclusive \psitwos cross section, at forward \rapidity, measured in pp collisions at $\s = 5.02$, 7~, 8~, and 13~ TeV (top panel), and ratio of the measurements at 5.02, 7, 8 TeV to the 13 TeV data (bottom panel). The data are compared with the NRQCD theoretical calculations from Butenschön~\etal~+ FONLL (left panel)~ and with theoretical calculations from ICEM + FONLL (right panel)~.
