Model - GMSB decays of ??????G - pair production
ggMEtX Sample - 760 pb-1 - 2 photons, Etgt25,
hlt1.1 Remove fake MEt - MEt not opposite the
largest jet - photon preshwr points to
vertex Background from jets - Two loose photons
sample - Normalize to low MEt
Background from W?en - Identify eg MEt sample -
Scale by prob for e to fake g

Model Limit - Snowmass Slope SPS 8 - c02c?1 and
c?1c?1 production - K-factor 1.2 - Limit

Model - 2 Higgs doublets - Fermiophobic, h?g g -
hVV coupling suppressed - hH? ?h(hW?)
?(gg)(gg)X - Search for gggX Data - 3 central
photons - Et gt 30, 20, 15 GeV - 830 pb-1 - Total
Pt of the 3g gt 25 GeV

Define matrices - True n (nggg nggj ngjj

Background - before final Pt(ggg) cut - QCD
0.72 ? 0.15 - Direct ggg derived from gg with a
similar matrix, and Pythia ggg/gg rate
2.73?0.55 - W/Zg and gg is small - Total 3.5 ?
0.6 Observed 5 events
- mass of all pairs
21
Limits - After the final Pt cut 1.1?0.2
expected, 0 observed - Higgs mass greater than 44
to 80 GeV, depending on H? mass and tanb
