Charge Independence and Symmetry of Nuclear Forces
Charge independence and symmetry are approximate symmetries of nature. The observations of the small symmetry breaking effects and the consequences of those effects are reviewed. The effects of the mass difference between up and down quarks and the off shell dependence q 2 of ρ 0-ω mixing are stressed. In particular, I argue that models which predict a strong q 2 dependence of ρ 0-ω mixing seem...
متن کاملη decays involving photons ∗
The decays of the η meson are reviewed in the framework of Chiral Perturbation Theory. Particular attention is devoted to the electromagnetic channels involving photons, either in the final or intermediate states.
متن کاملCalculations of Nuclear Reactions of Astrophysical Interest Involving Unstable Nuclei
Nuclear reactions involving unstable nuclei play an important role in nucleosyn-thesis. Such reactions are mainly associated with explosive astrophysical scenarios occurring at the nal stages of stellar evolution. For many nuclear reactions involving unstable nuclei the direct reaction mechanism cannot be neglected and may even be the dominant reaction mechanism. For example, the direct{reactio...
متن کاملCharge Independence and Charge Symmetry
Charge independence and charge symmetry are approximate symmetries of nature, violated by the perturbing effects of the mass difference between up and down quarks and by electromagnetic interactions. The observations of the symmetry breaking effects in nuclear and particle physics and the implications of those effects are reviewed.
متن کاملNuclear Reactions of Astrophysical Interest Involving Light Nuclei
An introduction to nucleosynthesis, the creation of the elements in the big bang, in interstellar matter and in stars is given. The two–step process He(2n,γ)He and the reverse photodisintegration He(γ,2n)He involving the halo nucleus He could be of importance in the α–process in type–II supernovae. The reaction rates for the above processes are calculated using three–body methods and show an en...
