Observation of the Xi_b^0 Baryon
Peter Bussey (for the CDF Collaboration)
TL;DR
This paper reports the first observation of the ^0 baryon and a new decay mode of ^-, both decaying into plus a charged pion, with high statistical significance, advancing understanding of heavy baryon states.
Contribution
It provides the first observation of the ^0 baryon and identifies a new decay mode for ^-, expanding knowledge of heavy baryon decays.
Findings
Observation of ^0 baryon with >6.8 sigma significance.
Detection of a new decay mode of ^- baryon.
Confirmation of decay into plus a charged pion.
Abstract
The first observation of the heavy baryonic state \Xi_b^0 is reported by the CDF Collaboration. A new decay mode of the established state \Xi_b^- is also observed. In both cases the decay into a \Xi_c plus a charged pion is seen, with an equivalent statistical significance of above 6.8 sigma.
