Abstract
The minimum supersymmetric standard model with bilinear R-parity
violation
is studied systematically. As we consider low-energy supersymmetry,
we examine
the structure of the bilinear R-parity violating model carefully.
We analyze the mixing of, e.g., Higgs bosons
with sleptons, neutralinos with neutrinos and charginos with
charged leptons in the
model. Possible and some important physics results, e.g.
that the
lightest Higgs
may be heavier than the weak Z-boson at tree level,
are obtained. The Feynman rules for the model are derived in
the 't Hooft-Feynman gauge, which is convenient if perturbative
calculations are needed beyond
the tree level.
