Popis: Charm production in charged current deep inelastic scattering has been measured for the first time in e ± p collisions, using data collected with the ZEUS detector at HERA, corresponding to an integrated luminosity of 358 pb−1. Results are presented separately for e + p and e − p scattering at a centre-of-mass energy of $$ \sqrt{s} $$ s = 318 GeV within a kinematic phase-space region of 200 GeV2 < Q 2 < 60000 GeV2 and y < 0.9, where Q 2 is the squared four-momentum transfer and y is the inelasticity. The measured cross sections of electroweak charm production are consistent with expectations from the Standard Model within the large statistical uncertainties.
