Query: MassToMI - a Mathematica package for an automatic Mass Insertion
  expansion   We present a Mathematica package designed to automatize the expansion of QFT
transition amplitudes calculated in the mass eigenstates basis (i.e. expressed
in terms of physical masses and mixing matrices) into series of "mass
insertions", defined as off-diagonal entries of mass matrices in Lagrangian
before diagonalization and identification of the physical states. The algorithm
implemented in this package is based on the general "Flavor Expansion Theorem"
proven in Ref.~\cite{FET}. The supplied routines are able to automatically
analyze the structure of the amplitude, identify the parts which could be
expanded and expand them to any required order. They are capable of dealing
with amplitudes depending on both scalar or vector (Hermitian) and Dirac or
Majorana fermion (complex) mass matrices. The package can be downloaded from
the address www.fuw.edu.pl/masstomi.
