Doubly Charmful Baryonic B Decays

There are two apparent puzzles connected with the two-body and three-body doubly charmed baryonic B decays. First, earlier calculations based on QCD sum rules or the diquark model predict B(B → Ξc Λ̄−c ) ≈ B(B 0 → BcN), while experimentally the former has a rate two orders of magnitude larger than the latter. Second, a naive estimate of the branching ratio O(10−9) for the color-suppressed three-...

We study the cancellations among Feynman diagrams that implement the Ward and SlavnovTaylor identities corresponding to the conserved supersymmetry current in supersymmetric quantum field theories. In particular, we show that the Faddeev-Popov ghosts of gaugeand supersymmetries never decouple from the physical fields, even for abelian gauge groups. The supersymmetric Slavnov-Taylor identities p...

The controversy about a Cambrian “explosion” of morphological disparity (followed by decimation), cladogenesis and fossilization is of central importance for the history of life. This paper revisits the controversy (with emphasis in onychophorans, which include emblematic organisms such as Hallucigenia), presents new data about the Chengjiang (Cambrian of China) faunal community and compares ii...
