“…In order to snapshot the coreexcited molecule at the time of the Auger decay, we examine the linear momenta of the fragments B þ and three F þ produced from the parent molecular ion BF 4þ 3 , measured in coincidence. The vector correlation among the linear momenta of three particles produced by three-body break-up can be well represented by the Dalitz plots [48]. Fig.…”

“…It is therefore necessary to model the variation of the efficiency, and to account for the distribution of signal events, over the phase-space of the decay. The phase-space of the decay of a spin-zero particle to three spin-zero particles can be completely described by the Dalitz plot [31] of any pair of the two-body invariant masses squared. The situation for a baryon decay is more complicated due to the spins of the initial and final state fermions, but -4 -…”

Searches for Λ 0 b and Ξ 0 b decays to K 0 S pπ − and K 0 S pK − final states with first observation of theThe LHCb collaboration E-mail: rsilvaco@cern.chAbstract: A search for previously unobserved decays of beauty baryons to the final states K 0 S pπ − and K 0 S pK − is reported. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0 fb −1 of pp collisions. The Λ 0 b → K 0 pπ − decay is observed with a significance of 8.6 σ, with branching fractionwhere the uncertainties are statistical, systematic, from the ratio of fragmentation fractions f Λ 0 b /f d , and from the branching fraction of the B 0 → K 0 π + π − normalisation channel, respectively. A first measurement is made of the CP asymmetry, givingNo significant signals are seen for Λ 0 b → K 0 S pK − decays, Ξ 0 b decays to both the K 0 S pπ − and K 0 S pK − final states, and the Λ 0 b → D − s (→ K 0 S K − )p decay, and upper limits on their branching fractions are reported.

“…It was introduced by Dalitz in a nonrelativistic application [22] and then extended to the relativistic case by Fabri [23]. If the transition amplitude is constant over phase space and if additionally there is no final state interaction, the occupation of the Dalitz plot would be fully homogeneous because the creation in any phase space interval would be equally probable.…”

The near threshold production of K + K − pairs in proton-proton collisions has been investigated at the cooler synchrotron COSY below and above the threshold for the φ meson using the COSY-11 and ANKE facilities, respectively. The excitation function determined for the pp → ppK + K − reaction revealed a statistically significant enhancement close to the threshold which may plausibly be assigned to the influence of the K − p interaction. In addition, observed consistently by both groups, a strong enhancement at low values of the ratio of the K − p to K + p invariant mass distributions shows that the proton interacts much stronger with K − than with K + . In this report we focus on the measurements performed by the COSY-11 collaboration. We explain the experimental method used and present main results of completed analyses as well as a new qualitative elaboration of the ppK + K − events population on the Goldhaber plot. We conclude with the observation that event densities increase at the region where the influence from the K + K − interaction is expected.
