Hi all,

Here are the replies from the Lambda_b proponents. They addressed our comments. We also had one physics comment:

Physics: We are very surprised that the observation of P asymmetry in Lb->Lcpi is only reported in the supplementary material. There has never been P violation seen in Lb decays. Why not report it? Adding a systematic uncertainty would take a bit of work, but is it that much?

  ---> For this paper we decided to focus on a couple of decay channels which are the most interesting for CPV. In the coming months, we will finalise the work on the other phhh decays. There we could also add the observation of P asymmetry in Lb->Lcpi decays.

Generally it's fine that one comes back to that in a later publication, though I doubt it will be a "few" months. The risk that some theorist makes big claims is rather low in that case (P violation in weak baryon decays, so what? That was already seen in 1956). So I suggest not to follow up.

Cheers,

Patrick
