Higgs & Top at LHeC

Satoshi orally reported about the Delphes card fix for version 3.3.3
which he circulated during last week.  Uta said she is checking
version 3.4 with a student, and encouraged Satoshi (and others) to do
the same.  She is also talking with Mukesh on the option to try
several HF tagging methods within the same Delphes generation.

Tanaka-san showed updates on his FCC Januray week analysis on FCC-eh,
which did not have photoproduction veto of 90%.  He optimized the
analysis with Delphes 3.1.2.  He also compared the Delphes 3.3.3 results with Satoshi's
fixed cards, and confirmed that his fix brings back almost the same as
3.1.2.  Uta noted that still the number of jets is smaller in 3.3.3 so
it is worth looking at version 3.4.

Uta commented that we should select a suite of signal events for checking our card file.
- one for Hbb (Liverpool, Tokyo Tech)
- one for NC top (Ilkay, Orhan)
- one for muons! -> we may use H-> mumu
- one for photons -> we may use H-> gamma gamma

We also discussed the effect of polarisation on distributions (Kechen) and that we should check this in particular for NC DIS (gamma and Z-interference effects!)

Ilkay reported on updates on FCNC top coupling study.
