| Abstract |
Analyses of high transverse momentum particle production are presented from the H1 data taken so far at the upgraded HERA collider in e+ p scattering data with longitudinally polarised leptons (HERA-II). The integrated luminosity is comparable with that produced in the first phase of HERA running (HERA-I). A general search for new physics is presented based on all final states with at least two high transverse momentum electrons, muons, photons, jets or neutrinos. Dedicated analyses are performed on final states with isolated electrons and muons and missing transverse momentum and with high mass multi-electrons, where excesses over Standrard Model predictions were observed in H1 HERA-I data. |
