Top control region

[lucalavezzo]

Invert b jet selections, and start looking at it.

Different top backgrounds, contamination from signal, other backgrounds, possible ABCD method variables.

contamination from signal

including from ttH. I recall that ZH may have a private sample for this?

[lucalavezzo]

Joey has privately produced ttH samples, and those have been added to filelists in #316. We are currently investigating this CRTT.

This region looks really good except for contamination from ttH signal. There was ideas of adding a selection on the BV(SUEP, jet), or a cut on sphericity to reduce this further, or perhaps use the offline/scouting analyses limits on the ttH signal directly, all of which work.
