Charm production in charged current deep inelastic scattering at HERA

Charm production in charged current deep inelastic scattering has been measured for the first time in e${}^{\pm }$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 $\sqrt{s}$ = 318 GeV within a kinematic phase-space region of 200 GeV${}^2$ < Q${}^2$ < 60000 GeV${}^2$ 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.
