Next-generation nucleon decay experiments

Nuclear Physics B - Proceedings Supplements, 2005
A recent status and future prospect of nucleon decay experiments are summarized. The most stringent limits on proton decays are given by the largest water Cerenkov detector, Super-Kamiokande. A lower limit on the partial lifetime of a proton is set at 5.4 × 1033 years for p → e+π0 at 90% C.L., and 2.2 × 1033 years for p → ν ¯ K + . A next

Rare Decays and the Fourth Generation

Annals of the New York Academy of Sciences, 1989
Rare decays are quite sensitive1 to physics beyond the Standard Model (SM), due to the effects of virtual, new, heavy particles (i.e., a fourth generation, SUSY, charged Higgs, E6 exotic fermions,…). These new contributions can either enhance or suppress (sometimes quite substantially) the rates for rare processes compared to the corresponding SM ...

Fourth generation and nucleon decay in supersymmetric theories

Physical Review D, 1987
Analysis of nucleon decay in N=1 supergravity unified models including the effect of a fourth generation of matter is given. Experimental constraints from nucleon-lifetime limits on the Kobayashi-Maskawa (KM) matrix that enters nucleon decay are obtained.

The generation and decay of vorticity

Geophysical & Astrophysical Fluid Dynamics, 1984
Abstract Vorticity, although not the primary variable of fluid dynamics, is an important derived variable playing both mathematical and physical roles in the solution and understanding of problems. The following treatment discusses the generation of vorticity at rigid boundaries and its subsequent decay.

Fourth generation effect on $��_b$ decays

2010
The rare decays of $ _b$ baryon governed by the quark level transitions $ b \to s$, are investigated in the fourth quark generation model popularly known as SM4. Recently it has been shown that SM4, which is a very simple extension of the standard model, can successfully explain several anomalies observed in the CP violation parameters of $B$ and $B_s$

Generalized entropy decay rates of one-dimensional maps

Physical Review A, 1988
A series of entropies, approaching the order-q Renyi's entropies when the length of orbits tends to infinity, is considered. Their scaling form is determined for chaotic one-dimensional maps. For the characteristic relaxation time a general expression is derived, and it is shown to be closely related to the eigenvalues of a generalized Frobenius-Perron

Generalized Floquet theory for decaying states

Radiation Effects and Defects in Solids, 1994
Abstract By solving a model photodetachment problem, we show how the standard Floquet wave function for a system driven by a harmonic potential is modified by the presence of coupling to the continum.
