Forward–backward asymmetry in electron–positron annihilation into pion or kaon pairs revisited

, 2020
Forward–backward (charge) asymmetry in the processes of [Formula: see text] annihilation into a pair of charged pseudoscalar mesons is recalculated in the one-loop approximation. The exact dependence on the meson masses is taken into account.

Electron-Positron Annihilation

Concepts of Elementary Particle Physics, 2019
This chapter works out the theory of electron-positron annihilation to muon pairs as a model for electron-positron annihilation to quarks. It explains that this naive model provides a good description of observed properties of the process of electron ...

Resummation of small-x double logarithms in QCD: semi-inclusive electron-positron annihilation

, 2011
We have derived the coefficients of the highest three1/x-enhanced small-x logarithms of all timelike splitting functions and the coefficient functions for the transverse fragmentation function in one-particle inclusive e+e− annihilation at (in principle)
