    Semi-exclusive production of photons at HERA

    We study the feasibility of measuring the semi-exclusive photon production \(\gamma + p \to \gamma + Y\) at HERA. The cross section of photons produced at large transverse momen...

    Soft and hard Pomeron in the structure function of the proton at low x and low \(Q^2\)

    We study inclusive electroproduction on the proton at low x and low \(Q^2\) using a soft and a hard Pomeron. The contribution of the soft Pomeron is based on the Stochastic Vacu...

    Dispersion Theoretical Analysis of the Nucleon Spin Polarizabilities

    The spin polarizabilities of the nucleon have been calculated from pion photoproduction data using forward dispersion relations. The feasibility of an experimental determination of these structure constants is...
