Effects of gravitational smearing on predictions of supergravity grand unification
Limits on gravitational smearing from the dominant dimension 5 operator (with strength characterised by $cM/2M_{Planck}$) are obtained using the LEP data in supersymmetric SU(5) grand unification. Effects of c on the quasi infrared fixed point solutio ns of $m_b/m_{\tau}$ unification are also analysed. It is found that $c>0$ softens and …
