摘要：

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 root 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.
