New physics effects in rare Z decays
نویسنده
چکیده
Virtual effects induced by new physics in rare Z decays are reviewed. Since the expected sensitivity of the giga–Z linear collider is of the order of 10, we emphasize the importance of any new physics effect that gives a prediction above this limit. It is also pointed out that an improvement on the known experimental constraints on rare Z decays will provide us with a critical test of the validity of the standard model at the loop level.

New Physics in CP Asymmetries and Rare B Decays
We review and update the effects of physics beyond the standard model on CP asymmetries in B decays. These asymmetries can be significantly altered if there are important new-physics contributions to B q -B 0 q mixing. This same new physics will therefore also contribute to rare, flavor-changing B decays. Through a study of such decays, we show that it is possible to partially distinguish the d...
متن کاملLong-distance effects in rare and radiative K decays
The electroweak structures of the FCNC-induced rare and radiative K decays are presented. While the former decays are sensitive to short-distance physics and offer exceptional probes for new physics, the latter are dominated by long-distance physics. Even so, they should not be set aside since they constitute essential ingredients to control the hadronic uncertainties occurring for the rare dec...

We examine the indirect effects of new physics on a variety of processes in the B system, such as the Z + bb vertex, the decays B + X,y and B + X,/+/-, and CP violation. 1. Introduction The investigation of virtual effects of new physics provides tunity to probe the presence of interactions beyond the Standard an important oppor-Model (S M). Various types. of.experiments may expose the existenc...
متن کاملSU(2)×U(1) gauge invariance and the shape of new physics in rare B decays.
New physics effects in B decays are routinely modeled through operators invariant under the strong and electromagnetic gauge symmetries. Assuming the scale for new physics is well above the electroweak scale, we further require invariance under the full standard model gauge symmetry group. Retaining up to dimension-six operators, we unveil new constraints between different new physics operators...
متن کاملRare Z Decays ∗ a † Gad
The central role played by rare decays on our understanding of elementary particle physics, is well known, where “rare” stands here for Flavor Changing Neutral Currents (FCNC), which are either small or practically vanishing in the SM. Some highlights: are: 1. In K physics: The first appearance of charm in loops from which mc ≈ 1.5 GeV was predicted [2]. 2. In B physics: The importance of b → s...
