摘要:

AbstractRare kaon processes appear to be particularly suitable to study the extensions of the standard model, especially if the possibility for eventual direct evidence becomes unlikely. In this review, we discuss processes that are important as a test of either the standard model or supergravity. Moreover, some of these are important even for both the standard model and for supergravity.Particular attention is paid to the reduction of uncertainties in the calculation, especially the ones coming from the confinement effects. Recent approaches, such as chiral perturbation theory, the largeNc‐expansion, QCD sum rules and lattice QCD, are discussed. This is found to be the best strategy in view of the fact that supersymmetric effects are rather tin

摘要:

AbstractWigner functions of permutation operators are obtained and are used as a basis for a phase space formulation of quantum identical particles. Non‐spin systems as well as 1/2 spin systems are considered. The general results are applied to a couple of example

摘要:

AbstractA description of equations forn‐point functions is presented in which notions from theoretical mechanics like generalized coordinates, constraints, systems released from constraints etc. are used. The case of strong interaction is described by the harmonic balance method and heuristic arguments are given concerning how to extend it for other interactions. Consistent use of projectors has significantly simplified the equations and formulas derive
