Of Ap Mass Spectrum from the Reaction : K - D - - - Pa at Rest
An experiment to study hyperon nucleon production in K-D interaction at rest \ was carried out by exposing the BNL 30-inch D2 bubble chamber to a low energy separated K-beam at the AGS. We present here results from the study of reaction K D-n-p A. In particular, a detailed analysis on the Ap mass spectrum near the 2129 MeV region was carried out to determine the nature of the observed enhanceme...

متن کاملA Study of Hyperon-nucleon Interaction in the Reaction: K-d -t-pa at Rest*
A Ap system with high statistics and mass resolution was studied in detail. The broad bump in the low mass region can be attributed to contribution from both the impulse and final state interaction mechanisms. The low energy Rp scattering parameters are deduced to be a0 = 2.0+ .5 and r. = 3.0&l. 0 fermi. The higher mass spectrum can be fitted to two Breit-Wigner resonant structures with Ml = 21...
متن کاملComment on “ Study of D sJ decays to D ∗ K in inclusive e + e − interactions ”
We comment on the recent observation of the decay mode D sJ (2860) → DK by the BABAR Collaboration [B. Aubert et al. (BABAR Collaboration), arXiv:0908.0806], and contest their peremptory conclusion that the data exclude a 0 assignment for the D sJ (2860). In particular, we argue that the observed branching fraction B(D sJ (2860) → DK)/B(D sJ (2860) → DK) = 1.1 ± 0.15 ± 0.19 supports the existen...
متن کاملStudies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
