Charge Independence and Charge Symmetry
نویسنده
چکیده
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.

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...

Charge symmetry breaking potentials due to the exchange of pseudoscalar and vector mesons in mirror nuclei are considered. With the computation of coulmb energy along with the present charge symmetry breaking effects provide a reasonably accurate description of the binding energy differences between mirror nuclei.

Some recent experimental and theoretical work on 1) charge symmetry-breaking, 2) parity non-conservation, and 3) searches for breaking of time reversal invariance are reviewed. The examples illustrate the uses of symmetry to learn about underlying dynamics and/or structure. INTRODUCTION Nuclei are known to be a superb laboratory for studies of symmetries and symmetrybreaking as well as tests of...

We review to what extent charge independence breaking (CIB) in isospin related reactions of the type NN → dπ can or could be seen in existing data. In doing this we present fits to global and threshold cross sections including most recent data. Applying these we point out the probable impossibility to make model independent predictions even based solely on the different threshold energies and t...
متن کاملParameter Identification of a Brushless Resolver Using Charge Response of Stator Current
Because of temperature independence, high resolution and noiseless outputs, brushless resolvers are widely used in high precision control systems. In this paper, at first dynamic performance characteristics of brushless resolver, considering parameters identification are presented. Then a mathematical model based on d-q axis theory is given. This model can be used for studying the dynamic b...
