Abstract

<jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>Charm production in charged current deep inelastic scattering has been measured for the first time in <jats:italic>e</jats:italic> <jats:sup>±</jats:sup> <jats:italic>p</jats:italic> collisions, using data collected with the ZEUS detector at HERA, corresponding to an integrated luminosity of 358 pb<jats:sup>−1</jats:sup>. Results are presented separately for <jats:italic>e</jats:italic> <jats:sup>+</jats:sup> <jats:italic>p</jats:italic> and <jats:italic>e</jats:italic> <jats:sup>−</jats:sup> <jats:italic>p</jats:italic> scattering at a centre-of-mass energy of <jats:inline-formula> <jats:alternatives> <jats:tex-math>$$ \sqrt{s} $$</jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> </jats:alternatives> </jats:inline-formula> = 318 GeV within a kinematic phase-space region of 200 GeV<jats:sup>2</jats:sup> &lt; <jats:italic>Q</jats:italic> <jats:sup>2</jats:sup> &lt; 60000 GeV<jats:sup>2</jats:sup> and <jats:italic>y</jats:italic> &lt; 0.9, where <jats:italic>Q</jats:italic> <jats:sup>2</jats:sup> is the squared four-momentum transfer and <jats:italic>y</jats:italic> is the inelasticity. The measured cross sections of electroweak charm production are consistent with expectations from the Standard Model within the large statistical uncertainties.</jats:p>
