This paper describes two beta decay experiments performed at the CERN/ISOLDE mass separator. The structure of Kr has been studied using a total absorption γ spectrometer (TAgS). The measured Gamow-Teller strength is presented and compared to HFBCS+QRPA calculations. The Na decay is also presented. The structure of the Mg daughter nucleus is compared to shell-model calculations, showing for the ...
We study the decays into six quarks of off-shell pairs of W± bosons produced in electronpositron annihilations, through the O(αs) order in the strong coupling constant. We give explicit helicity amplitude formulae. We present numerical results in the context of phenomenological analyses of relevance at LEP2 and future Linear Colliders: such as MW determinations, New Physics and Higgs searches. ...
In this paper, optimal distributed control of the time-dependent Navier-Stokes equations is considered. The control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. A mixed numerical method involving a quasi-Newton algorithm, a novel calculation of the gradients and an inhomogeneous Navier-Stokes solver, to find the opt...
