ResumoWe extend the standard QCD predictions, up to second order, to the scaling violation of the deep inelastic structure functions in the presence of light gluinos (supersymmetric partners of gluons). We show that these new particles give rise to scaling violations which are very close to the standard ones. Therefore present experimental data are also consistent with the existence of light gluinos of mass mλ < 10 GeV. Only more precise data would be able to conclude on their existence. All scaling violation effects observed in non-singlet and singlet structure functions are obtained with a single mass scale parameter Λeff. We also find the gluon and gluino distributions inside the nucleon, as a function of the gluino mass mλ.
