\noindent
At the Snowmass~2001 
{\em 'Summer Study on the Future of Particle Physics' } 
a concensus was reached to define a list of
SUSY models as benchmarks to be investigated in future collider studies.
Various scenarios, so-called 'Snowmass Points and Slopes' (SPS),
were proposed\footnote{
  {\em 'SUSY benchmark discussion'} at Snowmass 2001,
  http://lotus.phys.nwu.edu/~schmittm/snowmass %; \\
  }$^{,\,}$\footnote{
  M Battaglia et al, {\em 'The Snowmass points and slopes:
    benchmarks for SUSY searches'}, Snowmass pro\-ceedings,
  in preparation }  
in terms of a few parameters describing 
`typical' to `extreme' $R_p$ conserving supersymmetry breaking mechanisms of
mSUGRA, GMSB and AMSB. 
All benchmark points respect currently existing experimental constraints.

However, at Snowmass it was recommended 
to take the SUSY particle spectrum as generated by the program 
\isajet\footnote{
  H Baer et al, hep-ph/0001086, \isajet, 
  http://paige.home.cern.ch/paige}
as the reference for benchmark models,
instead of the few high energy parameters.
This arbitrary choice certainly does not imply that this program is superior 
to any other modern program.
In fact, the purpose of this note is to compare different codes and thus
to get a feeling on the reliability of presently available calculations.
We present SPS model spectra, i.e. using the same input parameters,
as generated by \isajet~7.58 in comparison with results from the programs
\susygen~3.00/27\footnote{ 
  N Ghodbane et al, hep-ph/9909499, \susygen, 
  http://lyoinfo.in2p3.fr/susygen/susygen3.html}
and \pythia~6.2/00\footnote{ 
  T Sj\"ostrand et al, hep-ph/0108264, \pythia, 
  http://www.thep.lu.se/$\sim$torbjorn//Pythia.html}.
These event generators are most popular and frequently used for 
SUSY studies and simulations.

\isajet \ uses the package {\sc Isasugra} to solve numerically the two-loop
RGE's in the MSSM couplings in the $3^{rd}$ generation approximation.
Theta-function thresholds are included in the gauge and Yukawa one-loop 
running couplings.
Decay modes are calculated with {\sc Isasusy} applying
decay matrix elements.
Besides generic MSSM models, specific scenarios can be selected with the 
mSUGRA, GMSB or AMSB options.

In \susygen \ the mSUGRA scenarios are calculated with 
the program \suspect~2.0\footnote{
  A Djouadi et al, hep-ph/9901246, {\tt SuSpect},
  http://www.lpm.univ-montp2.fr:6714/$\sim$kneur/ suspect.html}.
All masses and couplings (except scalar masses which are run at one-loop)
are evaluated numerically using two-loop RGE's 
in the $3^{rd}$ generation approximation
and including smooth thresholds.
The Higgs branching ratios are calculated using {\sc Hdecay}\footnote{
  A Djouadi et al, Comp. Phys. Comm. 108 (1998) 56}.
General models with a limited number of parameters can be chosen; 
GMSB and AMSB scenarios can be generated by setting 
the appropriate MSSM parameters.

\pythia \ is a fast and robust program and
uses semi-analytical formulae to solve the RGE's with one-loop
beta functions. Thresholds are not included.
Several SUSY models such as mSUGRA or fixed gaugino masses
can be chosen.
GMSB and AMSB scenarios can be realised via generic MSSM parameters.

In general all three programs provide mass spectra which agree at the
level of about 10\,\% for not too extreme choices of parameters.
However, huge mass differences of up to factors of 2 or even more
may occur in models with very large parameters, 
e.g high $m_0  \gg m_{1/2}$ (SPS~2) or high $\tan\beta$ (SPS~4). 
Such extreme situations are very sensitive to higher order corrections,
for which the programs may not be prepared.
In a study of SPS model lines it was observed\footnote{
  B C Allanach, 
  {\em `Theoretical uncertainties in sparticle mass predictions'},
  hep-ph/0110227}
that \isajet\ exhibits mass instabilities or wiggles as a function of
gaugino masses at the level of a few percent, 
but which may increase up to $\sim 30\,\%$ for the light chargino in SPS~3
depending on the value of $m_{1/2}$.

Another concern are the decay modes 
and branching ratios which are treated in the three programs
with different sophistication. Some of them seem to be incomplete, e.g. 
missing sfermion decays into gauge and Higgs bosons
and missing chargino decays into Higgs (\susygen) 
or missing Higgs decays into supersymmetric particles (\pythia).
Obvious problems arise due to mass differences, which may suppress 
or open certain decay channels. 
The user has to carefully examine the decay modes and possibly consult the
original literature.
For the Higgs sector dedicated programs like {\sc Hdecay}$^7$
or {\sc FeynHiggs}\footnote{S Heinemeyer et al, 
  Comp. Phys. Comm. 124 (2000) 76}
may be used as cross checks.

We adopt a user's point of view and feel unable to judge which is the 
optimal code or event generator to produce SUSY particle spectra.
However, if benchmark studies should be useful and should allow 
to do comparisons, we strongly advise the authors 
of future analyses to give the complete list of sparticle masses and
decay branching ratios which have been used.
In order to reproduce the \isajet\ spectra with \susygen\ and \pythia\ 
all necessary information is given in the SPS compilations below.
Besides the physical masses and branching ratios, 
further relevant MSSM parameters are:

Keeping in mind the previous remarks, we briefly comment the main
characteristics of the superparticle spectra obtained with the program
codes \isajet, \susygen\ and \pythia.
Note that there exist variants to SPS~1 and SPS~8 with $\tan\beta=30$,
leading to very similar spectra$^2$. 


\paragraph{SPS 1} 
The spectra of this `typical' mSUGRA scenario provided by the
three programs are in remarkable agreement with each other
to within a few percent.
Also the decay modes are reasonably similar.


\paragraph{SPS 2} 
Most striking in this `focus point' scenario with large $m_0 \gg m_{1/2}$
are the completely different neutralino and chargino
mass spectra of all three programs.
Factors of 2 with respect to some central value may easily occur.
This is related to the derived values of $\mu$ which exhibit discrepancies 
of the same order, casting doubt on the calculations.
The other sparticle masses are in reasonable agreement with each other.
However, large controversies exist in the treatment of the decays.
The heavy sleptons and squarks can decay via all charginos and neutralinos,
which apparently do have completely different gaugino and
higgsino admixtures, thus leading to different $\chi$'s in the final states.
This model as a whole needs certainly more care and a better 
theoretical understanding.


\paragraph{SPS 3} 
All spectra of this scenario which lies on a model line into
the `coannihilation region' are in good agreement with each other.
The masses differ within a few up to ten percent, some 
branching ratios may need to be adjusted.


\paragraph{SPS 4} 
In general the mass spectra are consistent to within 10\%. But due to the
high $\tan\beta$ value larger discrepancies are observed for the third
generation of sleptons and squarks and for the Higgs sector of \pythia.
The original purpose of this parameter choice was to provide a model with
relatively light Higgs bosons. 
At the time of the Snowmass meeting$^1$ a value of $m_A \simeq 310~\GeV$
was supported by \isajet~7.51 and \suspect~2.0 (point d'Aix~3).
Meanwhile the new release \isajet~7.58 gives a considerably
higher mass $m_A = 404~\GeV$, 
probably a consequence of a new treatment of the Yukawa bottom
coupling at two-loops in the RG evolution 
Similarly, if \suspect\ takes into account additional radiative corrections 
to all squarks and gauginos, one also gets a larger value of 
$m_A = 354~\GeV$.
Thus, in this parameter space with large $\tan\beta$
the Higgs spectrum depends sensitively on the 
details of higher order corrections. 
This also explains the lowish Higgs masses of \pythia, which uses a one-loop
approximation.


\paragraph{SPS 5} 
The sparticle spectra of all three programs are in general agreement.
But the scalar top $\st_1$, which should be light in this scenario,
is about 20\% heavier in \pythia.
This leads to quite different decay modes.


\paragraph{SPS 6} 
Very good agreement among the spectra is observed, since 
in this mSUGRA like scenario with non-unified gaugino masses
the MSSM parameters
calculated by \isajet\ serve as input to \susygen\ and \pythia.
Slight discrepancies occur in the branching ratios.


\paragraph{SPS 7 \& 8}
Only \isajet\ is able to generate genuine GMSB scenarios.
Since the gravitino is incorporated,
the MSSM parameters of \susygen\ and \pythia\ 
are adjusted accordingly.
\pythia\ does not offer to treat $\ti\tau_1$ as NLSP (SPS~7).
All the masses are in agreement by construction, except for
discrepancies of 5 - 20\% in the heavy Higgs sector of \susygen;
for the time being a more precise tuning appears problematic.
Again there are some differences in the decay channels, 
most important are those of $\ser$ and $\smur$ decays in model SPS~7.
The specified parameters do not fix the lifetime of the NLSP, 
which depends on the fundamental scale $\sqrt{F}$ of SUSY breaking.
\isajet\ allows to set this scale, such that finite decay length
distributions $c \tau \sim F^2 \cdot m^{-5}_{NLSP}$ of the NLSP can be studied.


\paragraph{SPS 9} 
An elementary treatment of AMSB scenarios is only possible in \isajet.
Using the corresponding MSSM parameters the appropriate spectra can be produced
with \susygen\ and \pythia .
Again there are some inconsistent decay modes, e.g. $\ser$ and $\smur$ decays
and, more important, the $\ch_1$ decays.
The characteristic feature is the near degeneracy of the lightest chargino 
and neutralino masses, which critically determines the $\ch_1$ lifetime and
decay modes.
The present parameters give $\tau = 165$~ps ($c \tau = 50$~mm).
The lifetime and proper branching ratios 
determine the $\ch_1 / \nt_1$ search strategy 
and it is advisable to consult the literature\footnote{
  J F Gunion, S Mrenna, Phys. Rev. D 64 (2001) 075002}.



\paragraph{Conclusions}
The three event generators \isajet, \susygen\ and \pythia\ produce consistent
supersymmetric particle spectra for a wide range of commonly accepted SUSY
parameters. However, severe discrepancies exist for scenarios with extreme
values of parameters, {\em e.g.} large $m_0 \gg m_{1/2}$ in the focus point
scenario SPS~2 (chargino and neutralino sector) and high $\tan\beta$ of SPS~4
(Higgs sector, $3^{rd}$ generation sleptons and squarks), 
where some particle characteristics depend sensitively on 
higher order corrections.
Although the programs are flexible enough to be adjusted to any mass spectrum
(including decay modes), 
it is {\em a priori} not obvious which program to prefer.
It is the aim of the present compilation to provide detailed information
and to help those who are interested to study the properties of the Snowmass
benchmark models.
