Isospin splitting in heavy baryons and mesons.
A recent general analysis of light-baryon isospin splittings is updated and extended to charmed baryons. The measured Σc and Ξc splittings stand out as being difficult to understand in terms of two-body forces alone. We also discuss heavy-light mesons; though the framework here is necessarily less general, we nevertheless obtain some predictions that are not strongly model-dependent. 13.40.Dk, ...
متن کاملΣC: A Programming Model and Language for Embedded Manycores
We present ΣC, a programming model and language for high performance embedded manycores. The programming model is based on process networks with non determinism extensions and process behavior specifications. The language itself extends C, with parallelism, composition and process abstractions. It is intended to support architecture independent, high-level parallel programming on embedded manyc...
متن کاملChiral Lagrangians for radiative decays of heavy hadrons.
The radiative decays of heavy mesons and heavy baryons are studied in a formalism which incorporates both the heavy quark symmetry and the chiral symmetry. The chiral Lagrangians for the electromagnetic interactions of heavy hadrons consist of two pieces: one from gauging electromagnetically the strong-interaction chiral Lagrangian, and the other from the anomalous magnetic moment interactions ...
متن کاملSpin and Isospin Asymmetry, Equation of State and Neutron Stars
In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.
متن کاملحالات مزونها و وابستگی آنها به اسپین و ایزواسپین
Meson is composed of one quark and one antiquark moving under the effect of confinement, oscillating and color potentials. Since quarks are particles with spin , there is a spin-spin interaction potential. Also we have isospins for u and d quarks and we can consider related potentials on isospin-isospin and spin-isospin effects. By comparing the given meson spectrum with the amount calculated...
