We have measured the branching fraction of tau/sup -/..-->..rho/sup -/..nu../sub tau/ to be (22.3 +- 0.6 +- 1.4)% and the branching fraction of tau/sup -/..-->..K/sup asterisk-/..nu../sub tau/ to be (1.3 +- 0.3 +- 0.3)%. These values are consistent with the expectations for conventional decays of the tau.

The branching fractions for the major decay modes of the tau lepton are measured from a sample of tagged tau decays selected from tau/sup +/tau/sup -/ pairs produced in e/sup +/e/sup -/ annihilation. The decay products of one member of the tau/sup +/tau/sup -/ pair are used to identify the event. The opposite member of the pair is then included in the ...

The n-1-->n fractional parentage coefficients (FPC's) for the jj-coupling states with equivalent particles in a j shell are calculated by using the branching rules for the unitary group U(2j+1) and the recurrence formula for the FPC's.
Using compartmental analysis methods, a mathematical basis is given for the measurement of absolute and fractional cardiac output with diffusible tracers. Cardiac output is shown to be the product of the blood volume and the sum of the rate constants of tracer egress from blood, modified by a factor reflecting transcapillary diffusibility, the transfer ...

We propose and demonstrate experimentally a new method based on the spatial entanglement for the absolute calibration of analog detectors. The idea consists on measuring the sub-shot-noise intensity correlation between two branches of parametric down conversion, containing many pairwise correlated spatial modes. We calibrate a scientific CCD camera and a ...

The deep oceanic circulation and in particular the North Atlantic deep water (NADW) is one of the major components of the climatic system. The accurate reconstruction of its past changes, although of the upmost importance, is however still controver- sial. Here we present a magnetic study for the last glacial period of cores from the Nordic seas and the North Atlantic. The uniformity of the ...
The branch process of the skyrmions in the fractional quantum Hall effect is studied from the phi-mapping topological current. It is shown that there exists a field ? whose Hopf indices and Brouwer degrees characterize the topological structure of the skyrmions. Based on the bifurcation theory of the phi-mapping theory, it is found that the skyrmions can ...
We examine how mixing between the Standard Model(SM) Higgs boson, h, and the radion of the Randall-Sundrum model modifies the expected properties of the Higgs boson. In particular we demonstrate that the total and partial decay widths of the Higgs, as well as the h {yields} gg branching fraction, can be substantially altered from their SM expectations, ...
The predictions of the standard electroweak model for the tau lepton decay modes are discussed and compared to experimental measurements. The measured tau lifetime, final state charged lepton momentum spectra, relative branching fractions and quantum numbers of hadronic final states all agree well with the standard model. However, the sum of the measured ...
