CORE 2.1 (COmpendium of RElations, Version 2.1)
The present CORE 2.1 (COmpendium of RElations, Version 2.1) contains various
formulas and relations used in the practical calculations in the Standard
Model. The properties of the Pauli, Dirac, Gell--Mann matrices, wave functions
of free fermions and gauge bosons are considered. We present the full
Lagrangian of the Standard Model and the corresponding Feynman rules. The
method of the evaluation of the Feynman (loop) integrals and calculations in
non-covariant gauges is considered. We discuss in brief the relativistic
kinematic and present a large number of the matrix elements of the various
processes in the Standard Model.Comment: 108 pages, the full text is submitted as four compressed and

Summary of the CMS Discovery Potential for the MSSM SUSY Higgses
This work summarises the present understanding of the expected MSSM SUSY
Higgs reach for CMS. Many of the studies presented here result from detailed
detector simulations incorporating final CMS detector design and response. With
30 fb-1 the h -> gamma,gamma and h -> bb channels allow to cover most of the
MSSM parameter space. For the massive A,H,H+ MSSM Higgs states the channels A,H
-> tau,tau and H+ -> tau,nu turn out to be the most profitable ones in terms of
mass reach and parameter space coverage. Consequently CMS has made a big effort
to trigger efficiently on taus. Provided neutralinos and sleptons are not too
heavy, there is an interesting complementarity in the reaches for A,H ->
tau,tau and A,H -> chi,chi.Comment: 19 pages, 27 figure
Search for Anomalous Top--Quark Interaction at LEP-2 Collider
We show that a search for
events at LEP--2 collider provide a possibility to improve significantly the
modern constraints on coupling constants of anomalous --quark interaction
via flavor--changing neutral currents.Comment: 12 pages, LaTeX, epsfig, 4 figures. Corrected typo
