“…For example, the prediction and discovery of the baryon, with strangeness S = −3, have been a spectacular confirmation of how well the SU(3) flavor symmetry works in strong interactions. Nevertheless, more than a half-century later, our knowledge of multistrangeness baryons is still very limited as can be seen from the fact that the spin of − (1672) was only recently confirmed [1,2].…”

Model-independent aspects of the reactionK¯+N→K+Ξ

View full text Add to dashboard Cite

Various model-independent aspects of theKN → K reaction are investigated, starting from the determination of the most general structure of the reaction amplitude for baryons with J P = 1 2 ± and 3 2 ± and the observables that allow a complete determination of these amplitudes. Polarization observables are constructed in terms of spin-density matrix elements. Reflection symmetry about the reaction plane is exploited, in particular, to determine the parity of the produced in a model-independent way. In addition, extending the work of Biagi et al. [Z. Phys. C 34, 175 (1987)], a way of determining simultaneously the spin and parity of the ground state of baryons as well as those of the excited states is presented.

Study of B-Meson Decays to Final States with a Single Charm Baryon

Majewski

2007

A study of B-meson decays to final states with a single charm baryon is presented based on data recorded by the BABAR detector at the Stanford Linear Accelerator Center. Although the B meson is the lightest bottom-flavored meson, it is heavy enough to decay to a baryon made of three quarks and an antibaryon made of three antiquarks. By studying the baryonic weak decays of the B meson, we can investigate baryon production mechanisms in heavy meson decays. In particular, we measure the rates of the decaysComparing these rates, we confirm an observed trend in baryonic B decays that the decay with the lower energy release,The dynamics of the baryon-antibaryon (Λ + c p) system in the three-body decay also provide insight into baryon-antibaryon production mechanisms. The B − → Λ + c pπ − system is a laboratory for searches for excited Σ c baryon states; we observe the resonant decays B − → Σ c (2455) 0 p and B − → Σ c (2800) 0 p. This is the first observation of the decay B − → Σ c (2800) 0 p; however, the mass of the observed Σ c (2800) 0 state is inconsistent with previous measurements.
