Recent results from ZEUS

摘要

The latest results concerning EW parameters, the as couplingcostant and flavour physics obtained from the ZEUS experiment at HERA are pre-sented. A new set of inclusive and jet cross-section measurements allowed ZEUS todetermine with good precision some EW parameters and also to have a measure ofas with the only HERA data, in agreement with the world average. Charm andbeauty cross-sections have been measured in different kinematic regions and used toextract the heavy-quark contribution to F2 structure function.
