Electroweak physics in e+-p scattering with polarised leptons
Kunihiro Nagano

HERA is the first and sole electron (positron) and proton collider. Deep inelastic scattering at large momentum transfer opened up by HERA brought various unique results to the high energy physics, for example a significantly deeper understanding of the proton structure. After a major upgrade HERA has started a new running phase since the year 2003, providing large luminosity and longitudinally polarised lepton beams (HERA-II). This is the first time polarised lepton and proton deep inelastic scattering is realized such that unique opportunities for electroweak (EW) studies at large scale are opened up. In this talk, a review of the hot results on EW physics from the latest HERA-II is presented.
