Backward-moving Altarelli-Parisi equations for transverse-momentum calculations in jets
Abstract
We develop equations for various jet-calculus propagators in which the mass of partons "evolves down" these are in some sense just the inverse of the normal Altarelli-Parisi equations in which the jet mass "evolves up." The new "backward-moving" equations are preferable for calculations of transverse-momentum distributions because they have a simpler separation of the transverse and longitudinal momentum variables.
