Heather Logan: At the moment, several people including
Heather
and Sven are looking at the constriant that will be made
to the MSSM
based on the measurements at the LHC. She has agreed
to look at how
this constraints become stronger if we have in addition
a gg-Higgs
factory and no e+e- machine available. Since we
are also including
h-->ZZ* in our analysis, we will consider the WW* and
ZZ* separeted
and combined.
Steve Asztalos: Steve is already working with the
latest PANDORA code
in order to check the impact of SUSY on the H--->bb analysis.
There are some issues still be improved by Peskin.
We will wait until
we get Steve's blessing of PANDORA to extend this
analysis to the other
decay modes.
Mayda Velasco: After some discussion it was agreed the
we will also look
at the a higher energy CLICHE to check the capabilities
at the same benchmarks
used by Haber and Van Kooten.
Michal Szleper: The analysis for h->aa in the gamma-gamma
mode has been
started. Pythia 6.158 was used to generate gamma+gamma->H
events, with
gamma-gamma luminosities obtained from CAIN. Masses
of H, A were
fixed by hand to their respective values from hep-ph/0305109
(6 cases) and H couplings manipulated in order to ensure
a close to
100% branching fraction for H->AA. The output H
width varied from
0.02 to 0.2 GeV, and branching fractions for A->bb and
A->tautau
were found close to the ones from hep-ph/0305109.
Overall
normalization will be defined by the SM gamma+gamma->h
cross
section. Background, coming mainly from 4-fermion
processes, will
be studied with WHIZARD.
Jack has pointed out that he expects gamma+gamma->h should
be SM
like, so this will be used as the criteria to check and
scale the
Pythia results.
Jack Gunion:
The Korea analysis from Jack et al on the radion assumed
that
e+e- was already available. The work will be repeated
assuming
no e+e-, and will give a list of the relevant benchmark
for radion-higgs mixing studies and gamma+gamma &
LHC constrains.
