Production of pions, kaons, and protons as a function of the relative transverse activity classifier in pp collisions at √s = 13 TeV
The production of π ±, K±, and (p ¯) p is measured in pp collisions at s = 13 TeV in different topological regions of the events. Particle transverse momentum (p T) spectra are measured in the “toward”, “transverse”, and “away” angular regions defined with respect to the direction of the leading particle in the event. While the toward and away regions contain the fragmentation products of the near
