We propose a model of inflation driven by minimal extension of SUSY, commonly
known as MSSM. Starting from gauge invariant flat directions in the n = 4 level
comprising of the combination QQQL,QuQd,QuLe and uude, we construct the
inflaton potential and employ it to investigate for its consequences around the
saddle point arising from the non-vanishing fourth derivative of the original
potential. To this end, we derive the expressions for the important parameters
in MSSM inflation using the loop corrected potential. We further estimate the
observable parameters and find them to fit well with recent observational data
from WMAP7 by using the code CAMB. We also explore the possibility of
primordial black hole formation from our model. Finally, we analyze one loop
RGE and compute different phenomenological parameters which could be precisely
determined in LHC or future Linear Colliders.
