CP-violating matrix elements, optimal observables:
In the publications concerning the search for CP-violation beyond the
Standard Model in the 4 jet
decays of the Z boson we propose several different analyses
for LEP 1 and SLC experiments. We encourage a lot to do such
analyses because one can get e. g. valuable information on the Higgs
sector.
In order to support such experimental analyses we can deliver
the relevant matrix elements in FORTRAN code for an implementation in
a Monte Carlo program. Some Monte Carlo studies to CP VIOLATION IN DECAYS Z
---> 4 JETS can be found in the talk and
in my PhD thesis.
In the latter you can find useful hints for the implementation of the
matrix elements as well.
Furthermore we can send
you the formulae of the
so-called "optimal observables" in FORTRAN code, which are very useful for
a measurement as explained in the two papers above.
In addition, for the implementation
of the matrix elements and the optimal observables for the analysis of THE
CP-VIOLATING TRIPLE GLUON INTERACTION IN Z ---> 4 JETS we provide a short
manual.
You like to get the code? Just send me an email:

Implementation of QCD Corrections into a Monte Carlo program for W boson
production at HERA:
The QCD Corrections in direct photoproduction of W bosons at HERA
are small compared to the results in leading order (LO) QCD. In addition,
the tails of differential
distributions are only hardly affected by the the next-to-leading (NLO) order
corrections (cf. hep-ph/0203269). Thus,
one can implement the NLO corrections by reweighting a LO Monte Carlo
program for W production at HERA.
A description of the procedure and the respective tables for the
reweighting constants can be found in hep-ex/0302040.
