Book excerpt: The study of hypernuclei affords unique insights into the nature of hadronic forces beyond those obtainable from ordinary nuclear physics research. A hypernucleus consists of one or more hyperons bound to a nuclear core. In the SU(3) classification, [Lambda], [Sigma], and [Xi] hyperons occupy the same octet representation of spin-parity /1/2/ baryons as the neutron and proton, the familiar constituents of ordinary nuclei. The [Lambda] and [Sigma] possess strangeness S = -1 and isotopic spin I = 0, 1, respectively, while the /Xi/ has S = /minus/2, I = /1/2/. In the underlying quark picture, the [Lambda] and /Sigma/ have the flavor structure s(ud)/sub I=0, 1/, compared to the combination uud for the proton. The strange quark, s, carries the strangeness quantum number S = /minus/1, which makes it distinguishable from the S = 0 u and d quarks. The lowest-lying hyperon is the /Lambda/, with a mass of 1,115.6 MeV/c2, some 177 MeV/c2 heavier than the proton. The study of the behavior of a hyperon embedded in the nuclear medium, through the theoretical analysis of level spectra, sheds light on the nature of the hyperon-nucleon (YN) effective interaction, i.e. on the role of the strange quark in strong interactions. This paper investigates the ([pi], K/sup +/) reactions that produce hypernuclei. 32 refs., 5 figs., 2 tabs.

Book excerpt: The authors study the feasibility of using the (K−, [eta]) reaction as a new tool for producing [Lambda]-hypernuclei. They compare the characteristics of the (K−, [eta]) reaction with those of the (K−, [pi]) and [pi], (K) reactions and calculate the production cross sections for the 12C(K−, [eta])[Lambda]12B reaction. Preliminary results of a test run at BNL to measure the ([pi]−, [eta]) and the (K−, [eta]) reactions are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Hypernuclei with strangeness -1 have been intensively studied both theoretically and experimentally using hadronic probes and reactions, (K, [pi]) and ([pi], K), for many years since the first discovery of such formation in the earlier nuclear emulsion and bubble chamber experiments. Many recent review papers exist on the status of hypernuclear physics, such as the recent one written by B.F. Gibson and Ed V. Hungerford in which one can find detailed discussion on all aspects of hypernuclear physics and more complete reference list. The unique feature of this field can be summarized, in general, into three categories: (1) Strong Interaction Involving Strangeness, (2) Weak Interaction with [Delta]S = -1, and (3) Medium Modifications. For strong interaction, it is commonly believed that a hyperon can be treated as an ''impurity'' to probe deep interior of the nuclear medium to explore fundamental issues such as the changes in size and shape due to the short range feature of YN interactions, limit of conventional nuclear model (shell or cluster) in solving for many body systems with new degree of freedom, spin dependent forces (spin-spin, spin-orbital, tensor), new symmetry and explicit QCD effect in nuclear media. Many of such issues are impossible or very difficult to be studied in the ordinary nuclear physics. The keys for success in this part of field includes good energy resolution and wide ranged spectroscopy. Until now, many important issues are still unresolved or remained to be resolved in more consistent and satisfactory fashion, such as spin dependent forces. This is due to luck of high quality experimental facilities. Recent experiments at KEK using ([pi], K) reaction with a dedicated new SKS spectrometer have demonstrated the importance of improving the energy resolution. New structures were found as resolution improved only from 3 MeV to 2 MeV.
