We present splitting functions in the triple collinear limit at next-to-leading order in the strong coupling. We performed the computation in the context of massless QCD+QED, and consider first collinear processes which include at least one photon. The IR divergent structure of the multi-partonic splitting functions agrees with the Catani's formula. Consistency checks based on symmetry...

Based on the non-relativistic QCD factorization scheme, we study the hadroproduction of the bottomonium states Υ(5S) and Υ(6S). We argue to search for them in the final states Υ(1S,2S,3S)π+π−, which are found to have anomalously large production rates at Υ(5S). The enhanced rates for the dipionic transitions in the Υ(5S)-energy region could, besides Υ(5S), be ascribed to Yb(10890), a state...
