Description
CERN - Tokyo Tech - Liverpool - Johannesburg

Satoshi (Kawaguchi-san) showed his bachelor thesis analysis on invisible Higgs search.
Mukesh commented that b.g. from SM decays of Higgs (like WW or ZZ) could be relevant.
Uta also supported the comment.  Uta asked why W+ and W- b.g. are so different.
Both suggested that forward jet could be used for selection.  A next step could be using MVA.

Tanaka-san showed his results on HCal resolution study, this time optimizing the selection cuts
for each set of resolution parameters.  Uta commented that the large difference between Set 6
and Set 9 (only the eta separation of resolution differs) is against intuition.  Tanaka-san will
look at it.  Uta commented that the coupling precision should be the optimization criterion,
and also polarization and photoproduction veto can help for better sensitivity.

Mukesh said he and Xifeng are looking at FCNC top efficiency study.
He also received referee comments for the HH paper.

Uta said her master student is studying the vertex resolution for
charm and b tagging.
He may report on the study in one of next meetings.  Rome FCC meeting
is imminent and inputs are welcome.
