Fourth level MSSM inflation from new flat directions
  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 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.
