In a previous paper, we proposed a simple extension of the Minimal Supersymmetric Standard Model which gives rise to thermal inflation and baryogenesis in a natural and remarkably consistent way. In this paper, we consider the λφ = 0 special case of our model, which is the minimal way to incorporate a Peccei-Quinn symmetry. The axino/flatino becomes the lightest supersymmetric particle with mã ...

We show that the renewal theory developed by Sarig and Gouëzel in the context of nonuniformly expanding dynamical systems applies also to the study of compact group extensions of such systems. As a consequence, we obtain results on subexponential decay of correlations for equivariant Hölder observations.

This result, obtained at the Stanford Linear Accelerator Center (SIX), is a prima facie demonstration of CP non-invariance in Kz" decay. It is consistent with theoretical expectations based upon an analysis of experimental data which has been obtained since the first such demonstration by Christenson, Cronin, Fitch and Turlay. (1) The analysis of KzO decay in terms of parameters characterizing ...

Predictions for decay rates and distributions for τ decays into final states with kaons are discussed and compared with recent measurements. Special emphasis is put on new constraints for the vector current contribution in the KKπ decay modes. For the Kππ modes, disagreements with the experimental results can be traced back to the K1 widths.

We investigate the dynamical properties of the radiation field emitted from an excited two-level atom in a photonic crystal. If the transition frequency of the atom lies within a certain frequency range above the band edge, the emitted field consists of two components that show a different decay dynamics. In particular it is shown that one field component decreases faster than the atomic popula...

Nobody's perfect, and even the cell turns out a certain fraction of erroneous mRNA transcripts. One of the key quality control mechanisms put in place to recognize and eliminate these transcripts before they can be translated into faulty proteins is nonsense-mediated decay. Proteins involved in nonsense-mediated decay are highly conserved across species from plants to humans, and recent studies...

In this study, thermoluminescence decay is investigated within Tsallis thermostatistics(TT). We belive that this is the first attempt to handle themoluminescence decay process within TT.

We evaluate pionic decay widths of Λ hypernuclei using a shell model for, both the nuclear bound and the continuum nucleon wave functions in the final state, and distorted waves for the outgoing pion. An excellent agreement with the recent KEK measurement of π −-decay widths of 12 Λ C and 28 Λ Si is found. Besides, results for 56 Λ Fe are consistent with the existing upper bound.

background and aims. the purpose of this study was to evaluate initial force and force decay of commercially available elastomeric ligatures and elastomeric separators in active tieback state in a simulated oral environment. materials and methods. a total of 288 elastomeric ligatures and elastomeric separators from three manufacturers (dentaurum, rmo, 3m unitek) were stretched to 100% and 150% ...
