|Recent results from the H1 collaboration at HERA.|
Abstract ======== New results from the H1 experiment at the electron-proton collider HERA are reported. As a complement to the results on photoproduction which are detailed in an other report in these proceedings, evidence for hard scattering in gamma diffraction in photoproduction events is presented. The hadronic final state in low x deep inelastic scattering (DIS) events has been analysed. Transverse energy flow and cross section for production of jets at high x(j) are compared to the expectations of present Monte Carlo programs and to analytical calculations based on the BFKL evolution equation. DIS interactions with no hadronic energy flow in a large interval of rapidity around the incident proton direction are presented. The data are compared to models based on deep inelastic pomeron scattering or on VMD contributions. Measured cross sections for the production of multijet in DIS events at HERA are used to provide a preliminary measurement of the strong coupling constant alpha(s) together with the first direct measurement of the gluon density in the proton. The cross section of the charged current process e- p --> nu(e) + hadrons is measured. The effects of the W propagator term is visible for the first time. New limits on leptoquarks, leptogluons, Squarks from R-parity violating supersymmetry and on excited leptons are given.
