Hi everyone,
We have received comments on our comments.
Looking through it quickly, about the large physics points: it seems that they indeed optimise S/(S+B) on MC, which is their “expected”.
... based on the peak they see before the BDT is applied. But they optimise using MC for signal, so that's at least not biasing. Please ask them to clarify this in the paper.
They gather the TIS efficiency from Monte Carlo. I’m surprised by their very low error on the trigger efficiency in the first place (0.1%). I wonder how they assign a systematic to this TIS thing…
Yes, please ask. Their just reply "Based on MC.", which is really not taking the question seriously.
Cheers,
Patrick
In the light of the winter conference deadlines, it would be nice to get back to them as soon as possible. Please let me know if you have anything else to add. I’ll try to send an answer at the end of tomorrow, or on Saturday if requested.
Good night, Laurent
