Higgs & Top at LHeC

Monday 9 Jan 2017, 11:00 → 13:00 Europe/Zurich

CERN - Tokyo - Liverpool - Johannesburg - Beijing - Hamburg

(1) Satoshi presented his results for "higgs->invisible" using the new Delphes card.

The precisions of Br(higgs->invisible) by applying MVA for new (old) Delphes card can be 5.65% (4.71%) at LHeC, and 2.65% (1.93%) at FCC-eh.

The new Delphes card gives a little bit worse precisions.

This might be due to the change of resolutions. 

 

(2) For Masahiro's "H->bb" analysis with 100 fb^-1 luminosity,

one gets precisions of 6.4% using the new LHeC Delphes card, and 4.8% using the old LHeC Dephes card.

At FCC-eh, the precision is 2.3%.

The differences of old and new LHeC Delphes card may mainly come from HCal setup.

 

(3) Orhan presented his top FCNC results using new Delphes card (modified for electrons).

He also compared the distributions using new FCC-ep card and FCC card.

 

(4) Subhasish reported one problem about electrons for the new Delphes card.

One cannot find electrons (perhaps also muons) after Delphes using the new Delphes card for "electrons + muons + b-quarks" final state.

Orhan may also find this problem.

They will communicate and send us about the details.
