Abstract

A next--to--leading order QCD analysis of deep inelastic scattering data is performed allowing for contributions due to a light gluino. We obtain the values of α_s(M_Z²) ± δα_s^stat = 0.108 ± 0.002, 0.124 ± 0.001, 0.145 ± 0.009 for QCD, SUSY QCD with a Majorana gluino and a Dirac gluino respectively. The value of \alsm obtained in SUSY QCD with a Majorana gluino best agrees with the direct measurements of α_s(M_Z²) at LEP.
