Abstract
A contact interaction analysis is presented to search for new phenomen a beyond the Standard Model in deep inelastic e(+/-)p-->e(+/-) hadrons scattering. The data are collected with the H1 detector at HERA and c orrespond to integrated luminosities of 0.909 pb(-1) and 2.947 pb(-1) for electron and positron beams, respectively. The differential cross sections d sigma/dQ(2) are measured in the Q(2) range between 160 GeV2 and 20000 GeV2. The absence of any significant deviation from the Sta ndard Model prediction is used to constrain the couplings and masses o f new leptoquarks and to set limits on electron-quark compositeness sc ales and on the radius of light quarks.
