Minutes and comments from  meeting on May 22:

1) CLICHE parameters:  In order to have work with machine
paramaters that are  more realistic we need to:
        - Reduce the repetion rate by at least a factor of 4
        this willmake the laser affordable (Gronberg),
        and also is the likely
        situation for  the initial stages of CLIC1.
        - Increase the bunch charge by a factor of 2 (Shultze).
        ==> Consequence, we need to produce new CAIN files. First
        tuned for 115 GeV Higgs like for our paper, later extend it
        to higher energies.

2) Physics models to be checked:

        - Higgs in case of diffent  SUSY Parameter (Sven H.)
        * Should include studies in case of Complex MSSM with
        H~55 GeV.  This will require CP-violation and h2-->h1h1
        ===> Sven will provide the required information fot the
        GammaGamma partial width and couplings.
        * Question from SVEN... Can we study the invissible
        decays?  Assume alreadyfound at LHC in ttH.
        * Should use the Bench mark proposed by Sven and company
        in:
        M.Carena, S.Heinemeyer, C.E.Wagner and G.Weiglein,
        ``Suggestions for benchmark scenarios for MSSM Higgs boson
        searches at hadron colliders,''
        Eur.\ Phys.\ J.\ C {\bf 26} (2003) 601
        [arXiv:hep-ph/0202167].

        ===> Michael Peskin has now implemented SUSY Br in Pandora,
        therefore this analysis can start.
 

        - NMSSM Scenario (Jack Gunion)
        * gg coupling is suppressed in some p[arameter space.
        Will study the case of h-->aa  where a-->bb, tau tau.
        This mode could be detected at LHC, but their mass determination
        will be dificult. So, that question is how well can we do?
        * This analysis can be extended to the case of CP-violation
        discussed by OPAL.
        ==> To Do Pythia has a-->bb and we have already disccussed
        the gg-->4 fermions, so this analysis can already start.
        Michal will work on it.

        - CP-phases and SUSY.  Not worth discussing at the moment....

        - Radion (Jack Gunion).  The studies that Jack did before
        Korea last year, assumed that we will have and e+e- machine
        first.  Now he will repite his analysis assuming that there
        is not e+e-.
        ===> We have the generator for gg-->ZZ, so we will
        check the impact of the radion in both bb and ZZ.
