Gluon bremsstrahlung $K$ factors in QCD and supersymmetric QCD

$K$-factor for the $q\overline q\to\Phi\overline\Phi$ process in $N=1$ SUSY QCD is calculated. The exact gluon bremsstrahlung matrix elements squared allowing for computation of the corresponding $K$-factors are obtained. As an illustration the $K$-factors for the processes $qq\to\Phi\Phi$, $GG\to\Phi\overline\Phi$ and basic processes of QCD are presented.
