Related paper First observation of ultra-long-range azimuthal correlations in low multiplicity pp and p-Pb collisions at the LHC The ultra-long-range (|Δη|>5.0) per-trigger yield, measured as a function of Δη and Δφ in p--Pb collisions at √sNN=5.02 TeV for ($7 < N_{\rm ch} < 40$), shows a double-ridge structure after non-flow removal using the template-fit method.
