14:40 → 15:00 Hadronic W-decay separation in H->WW* events

I am looking at hadronic W-decays in 500 GeV H -> WW* events, semihadronic channel.
I aim to separate W -> d+u from W -> s+c. These decay channels can be regularly c-tagged, but also have different amounts of kaons.
I take tracking-based PID info (dE/dx, V0, TOF) to find kaons and pions, and collect various observables linked to these particles.
I show that these observables have a certain separation power, which I compare to the performance of LCFIPlus-based c-tagging.
I show that by combining both vertex- and tracking-based information, a higher separation performance is achieved, in particular at high purities.

Speaker: Ulrich Einhaus (DESY)
