This is the first observation of a two-body baryonic Bdecay.
2
We exclusively reconstruct the companion Bdecay to suppress background.
3
Signal events are selected by examining the properties of the system recoiling against either a reconstructed hadronic or semileptonic charged- Bdecay.
4
The results provide both qualitative and quantitative new insights into CP -violation effects in hadronic Bdecays.
5
The analysis uses events in which the signal Bdecays are reconstructed with an innovative loose neutrino reconstruction technique.
6
We also report improved measurements of the momentum distributions of psi produced directly from Bdecays, correcting for measurement smearing.
7
We present updated measurements of time-dependent CP asymmetries in fully-reconstructed neutral Bdecays to several CP eigenstates containing a charmonium meson.
8
From the spectrum, we observe Omega(c)(0) production from Bdecays and in cc events, and extract the two rates of production.
9
These channels are of interest to study the mechanisms behind hadronic Bdecays, and open new possibilities for CP violation analyses with larger data sets.
10
CP-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two Bdecays.
