Abstract

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 s = 318 GeV within a kinematic phase-space region of 200 GeV² < Q² < 60000 GeV² and y < 0.9, where Q² 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.
