 gluon  gluon fusion
EW corrections

a grid for delta(EW) in gluon  gluon fusion. You will find three sets of data,
glu_m.dat,
glu_c.dat,
glu_p.dat,
corresponding to m(top) = 171.06, m(top) = 172.64, m(top) = 174.22,
with M(H)[GeV] and delta(EW)[%]
A safe estimate of the numerical error on the percentage corrections is
0.02 (it is < 0.003 below the WWthreshold,
remains < 0.009 up to the the ttthreshold and for some high values of M(H)
(> 500 GeV) it approaches 0.02).
Note that the grid is not uniform and it is denser around thresholds.

For your convenience we also add
EWgint.f a Fortran95 program for a cubic interpolating
spline incorporating the grid
all3.eps a plot of delta(EW)
These days people wants to plot lineshapes with very high invariant mass. You better use the
following grid:
ngridc.dat
Please stop at 2.5 TeV, estrapolation will never work. Suggestion is to stop at 1.8 TeV invariant
mass for Higgs mass less
than 700 GeV and to stop at 2 TeV for Higgs mass between 700 GeV and
1 TeV.
 H > gamma gamma
EW corrections
 H > gamma gamma
a grid for delta(EW) in gamma gamma decay. You will find three sets of data,
gam_m.dat,
gam_c.dat,
gam_p.dat,
corresponding to m(top) = 171.06, m(top) = 172.64, m(top) = 174.22,
with M(H)[GeV] and delta(EW)[%]
(other input parameters are like given in arXiv:0809.3667 [hepph])
A safe estimate of the numerical error
on the percentage corrections is 0.001 below the WWthreshold and
0.005 above it.
Note that the grid is not uniform and it is denser around WWthresholds.

For your convenience we also add
UpperLowerMt.eps
a plot of delta(EW) with the central value of m(top) in blue and the
"error band"
due to the lower and upper value of m(top) in red.
RealvsCMR.eps a plot showing, for the central value of
m(top), the result for complex masses(red) and
(up to the WWthreshold) the pure real masses(blue).

Disclaimer
the use of an onshell Higgs boson up to a mass of 1 TeV is a theoretical
nonsense and we should not be held responsible for the consequences.
Furthermore, EW twoloop corrections are growing with M(H) (although not
drastically).
There are reasons for that, i.e. the scalar sector of the SM becomes strongly
interacting
for very large values of M(H) (e.g. HHH etc. vertices) and, at twoloop, we
are testing
the full content of the SM. Furthermore, starting from the ttbarthreshold
the oneloop amplitude develops an increasing imaginary part and
the twoloop amplitude interferes with the oneloop one.

We propose, instead

Higgs PseudoObservables, Second Riemann Sheet and All That.

For your convenience we also add
c_dev.eps a plot with the effect of the new scheme
