    Higgs at LHeC

    Satoshi (Kawaguchi-san) presented his updates on invisible H search.  The BG from SM Higgs decay (WW, ZZ, etc.) turned out to be negligible after all cuts.  Comparing eta_j - eta_e and eta_j cuts, cutting with eta_j with the leading jet
    (rather than the most forward jet) gave the best S/sqrt(B).  Masahiro commented that H->lljj should be included in the CC Higgs BG.  Uta suggested to try MVA for further performance.

    Masahiro presented Tanaka-san's slides.  Optimization of Hbb was done based on optimal coupling precision rather than S/sqrt(B).  As a result both S and B increased, and all settings gave results better than 5% (for 100pb-1, unpolarized, unvetoed PHP).
