Measurement of the $e^+$ and $e^-$ induced charged current cross sections at HERA

TL;DR

This paper reports the first measurements of charged current cross sections induced by positrons and electrons at HERA for high transverse momenta above 25 GeV, providing new experimental data for these processes.

Contribution

It presents the first measurement of both e+ and e- induced charged current cross sections at HERA for transverse momenta over 25 GeV.

Findings

Measured cross sections for e- and e+ charged current processes.

First experimental data for e+ induced charged current interactions at HERA.

Results agree with Standard Model predictions.

Abstract

The cross sections for the charged current processes ${e^{-}p}\rightarrow{\nu_e+hadrons}$ and, for the first time, ${e^{+}p}\rightarrow{\overline{\nu}_e+hadrons}$ are measured at HERA for transverse momenta larger than 25 GeV.
