A measurement is presented of elastic deeply virtual Compton scattering e++p→e++γ+p at HERA using data taken with the H1 detector. The cross section measured as a function photon virtuality, Q2, and invariant mass, W, γp system, in kinematic range 2<Q2<20GeV2, 30<W<120GeV |t|<1GeV2, where t squared momentum transfer to proton. compared QCD based calculations.

A search for contributions to the reaction ep→eπ0N∗ from photon–odderon fusion in photoproduction regime at HERA is reported, an average photon–proton centre-of-mass energy 〈W〉=215 GeV. The measurement proceeds via detection of π0 decay photons, a leading neutron N∗ decay, and scattered electron. No signal observed upper limit on cross section process σ(γp→π0N∗)<49 nb 95% confidence level derived, integrated over experimentally accessible range squared four-momentum transfer nucleon vertex...

A search for scalar and vector leptoquarks coupling to first generation fermions is performed in the H1 experiment at ep collider HERA. The analysis uses e−p data collected 1998 1999 a centre-of-mass energy of 320 GeV, corresponding an integrated luminosity ∼15 pb−1. No evidence direct production such particles found sample with large transverse momentum final state electron or missing momentum, constraints on leptoquark models are established. For Yukawa electromagnetic strength excluded...

We propose to use an internal polarized hydrogen storage cell gas target in the AD ring determine for first time two total spin-dependent pbar-p cross sections sigma_1 and sigma_2 at antiproton beam energies range from 50 450 MeV. The data obtained are of interest by themselves general theory interactions since they will provide a experimental constraint spin-spin dependence nucleon-antinucleon potential energy interest. In addition, measurements polarization buildup stored antiprotons...

A search for excited electron (e∗) production is described in which the electroweak decays e∗→eγ, e∗→eZ and e∗→νW are considered. The data used correspond to an integrated luminosity of 120 pb−1 taken e±p collisions from 1994 2000 with H1 detector at HERA centre-of-mass energies 300 318 GeV. No evidence a signal found. Mass dependent exclusion limits derived ratio couplings compositeness scale, f/Λ. These extend excluded region higher masses than has been possible previous direct searches electrons.

We present a search for excited neutrinos using e−p data taken by the H1 experiment at HERA center-of-mass energy of 318 GeV with an integrated luminosity 15 pb−1. No evidence neutrino production is found. Mass dependent exclusion limits are determined ratio coupling to compositeness scale, f/Λ, independently relative couplings SU(2) and U(1) gauge bosons. These extend excluded region higher masses than has been possible in previous searches other colliders.
