On current conversion between particle rapidity and pseudorapidity distributions in high energy collisions

Abstract

In high energy collisions, one usually needs to give a conversion between the particle rapidity and pseudorapidity distributions. Currently, two equivalent conversion formulas are used in experimental and theoretical analyses. An investigation in the present work shows that the two conversions are incomplete. Then, we give a revision on the current conversion between the particle rapidity and pseudorapidity distributions. © 2013 Fu-Hu Liu et al.
