Tanaka-san showed the study on DeltaR dependence of
H->bb signal efficiency.  R=0.9 was used in PGS with kt jets,
but the same R with anti-kt gives too low efficiency.
By scanning, R=0.7 gives highest efficiency which is about
twice as large as R=0.9 and close to the previous PGS result.
Xifeng commented that the drop at R=0.4 is surprising, and
suggested to look at truth level b and non-b jets (using FASTJET).
Uta suggested to use the CAL resolution proposed by Max
in his email on 28/Oct, modified to:
eta < 2:  35%/sqrt(E/GeV) + 3%
2 < eta < 5:  45%/sqrt(E/GeV) + 5%.
Peter commented this is very demanding for hardware
developers, and should be taken as something we 'aim'.

Mukesh showed the cross section calculation for FCNC
top production in presence of anomalous couplings,
on gamma and Z vertices for u-t and c-t.
