Landau pole effects and the parameter space of the minimal supergravity model
It is shown that analyses at the electroweak scale can be significantly affected due to Landau pole effects in certain regions of the parameter space. This phenomenon arises because of a large magnification of errors of the input parameters ${\mathit{m}}_{\mathit{t}}$, ${\mathrm{\ensuremath{\alpha}}}_{\mathit{G}}$ which have currently a 10% uncertainty in their determination. …
