Dear all,
We would like to share with you the first glimpse of the unblinded Bc -> Bs Pi, using Bs -> Ds Pi. Under study is the partially reconstructed contributions (Bs* pi), (Bs rho).
For 2011+2012, the significance at this point is 4.1 sigma (excluding systematics).
Thanks, also on behalf of Niels, Jacco
Congratulations! That's a nice peak!
So what would be the Bc->Bspi BF (roughtly)?
Cheers,
Patrick

Thanks!
Using this fit, sigma(Bc)/fs x BR(Bc2BsPi) is [ 1.85 +- 0.46 (stat) + 0.37 - 0.35 (syst) ] x 10^-3
Which puts BR(Bc2BsPi) roughly to 19.9 +- 50% (rel.)
But we just discovered something is going wrong in the DTF, and it's not constraining the Bs mass. Working on this right now, and it should improve!
Cheers, Jacco
