dc.descriptionThe process e(+) e(-) -> n gamma (n>=2) are studied to estimate the total and differential cross sections of these reactions using the L3 data collected during 1991-1998 at centre of mass energies in the range 91-193 GeV. The lower limits obtained at 95% confidence level are, on a contact interaction enerygy scale Lambda > 1065 GeV, and on the mass of an excited electron m*_e > 263 GeV. The upper and lower limits on the gravitational size of fundamental particles are estimated using the model of selfgravitating particlelike structure with de Sitter core, which gives an estimate for self-coupling of the Higgs field lambda <= pi/16 and for the mass of the Higgs scalar m_H <= 154 GeV.
