A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave Kπ amplitude as a function of Kπ invariant mass. These are compared with results from K − π + elastic scattering, and the prediction of the Watson theorem , that the phase behavour be the same below Kη ′ threshold, is tested. Contributions from I = 1 2 and I = 3 2 are not reso...

In this letter we propose exact three-point correlation functions for N = 1 super-symmetric Liouville theory. Along the lines of [12] we propose a generalized special function which describe the three-point amplitudes. We consider briefly the so called reflection amplitudes in the supersymmetric case.

The existence of isospin admixtures in the physical Λ, π o complicates the extraction of ∆I = 3 2 non-leptonic hyperon decay amplitudes from experimental data, allowing contributions associated with large ∆I = 1 2 amplitudes to appear in the (nominally) ∆I = 3 2 amplitudes obtained ignoring these admixtures. We show how to correct for this effect to leading order in (m d − m u) and extract the ...

The aim of this paper is to study uniformly elliptic operators with general Wentzell boundary conditions in suitable Lp-spaces by using the approach of sesquilinear forms. We use different tools to re-prove analiticity and related results concerning the semigroups generated by the above operators. In addition, we make some complementary observations on, among other things, compactness issues an...

The most important practical characteristic of a Josephson junction is its critical current. The shape of the junction determines the specific form of the magnetic-field dependence of the its Josephson current. Here we address the magnetic diffraction patterns of specially shaped planar Josephson tunnel junctions. We focus on a wide ensemble of generalized ellipses, called superellipses, which ...

Introduction This procedure calculates the sample size necessary to achieve a specified distance from the difference in sample means to the confidence limit(s) at a stated confidence level for a confidence interval about the difference in means when the underlying data distribution is normal. Caution: This procedure assumes that the standard deviations of the future samples will be the same as ...

A generating function for a class of multigluon amplitudes is constructed as a particular solution of the self-duality equation.

purpose: the goal of this study was to compare differences in the mean heterophoria and fusional amplitudes before and after photorefractive keratectomy (prk) for myopia. methods: in a prospective controlled study, myopic patients were treated with aspheric and wavefront-guided (personalized) prk. the manifest refraction, visual acuity, fusional amplitudes and heterophoria were evaluated preope...

purpose : to determine the fusional amplitudes and the frequency of hetrophoria, in our patients methods : in this cross sectional study, 111 adults with mean age of 25.6 years were included. all participants had best corrected visual acuity (bcva) better than 20/25, more than 60 sec of arc stereopsis and had no heterotropia or other significant eye disorders. fusional amplitudes were measured ...

Forward-backward charge asymmetry in rare dilepton B-decays is formulated with the assumption of an on-shell b-quark. We find the asymmetry is expressed in terms of two spatially transverse helicity amplitudes, which are determined by combining the data of D → K(892) l+ν with heavy flavour symmetry. We estimate the charge asymmetry of B → K(892) l+l− for large energy leptons against various top...
