Hypernuclear Physics for Neutron Stars
The role of hypernuclear physics for the physics of neutron stars is delineated. Hypernuclear potentials in dense matter control the hyperon composition of dense neutron star matter. The three-body interactions of nucleons and hyperons determine the stiffness of the neutron star equation of state and thereby the maximum neutron star mass. Two-body hyperon-nucleon and hyperon-hyperon interaction...
متن کاملHypernuclear Physics and Compact Stars
Hypernuclear physics plays a decisive role for several features of compact star physics. I review the impact of hypernuclear potential depths, two-body hyperon-nucleon and hyperon three-body forces as well as hyperon-hyperon interactions on the maximum mass, the mass-radius relation, and cooling properties of neutron stars. PACS. 21.80.+a Hypernuclei – 26.60.+c Nuclear matter aspects of neutron...
متن کاملFragmentation and strangeness at PANDA
Hypernuclear physics offers the unique possibility to study the behaviour of the hyperon-nucleon (Y N ) and the hyperon-hyperon (Y Y ) interaction inside excited hadronic matter [1] at terrestrial laboratories, such as the FAIR facility at GSI, Darmstadt. Such investigations are important for a better understanding of the strangeness sector of the equation of state, a topic of current research,...
متن کاملHyperon Polarization and Vector Meson Production at 2.85 Gev (preliminary Results)
On Behalf of the DISTO Collaboration * Surprisingly large polarization in hyperon production by unpolarized proton beam has been known since long time. Huge inclusive hyperon polarization data are available in literature, few data are disponible on spin observables and none on exclusive hyperon measurements. Evidence of relevant violation of the OZI rule in several reactions are also shown in r...
متن کاملPolarization in Hyperon Photo- and Electro- Production
Multiple polarization observables must be measured to access the amplitude structure of pseudoscalar meson photoproduction off the proton. The hyperon-producing reactions are especially attractive to study, since the weak decays allow straightforward measurement of the induced and recoil polarization observables. In this paper we emphasize γ + p → K +Λ, discussing recent measurements of Cx, Cz,...
