Search for a scalar component in the weak interaction
/ Zakoucky, Dalibor (Rez, Nucl. Phys. Inst.) ; Baczyk, Pavel (CERN) ; Ban, Gilles (Caen U.) ; Beck, Marcus (Munster U. ; Mainz U.) ; Breitenfeldt, Martin (KU Leuven, Dept. Phys. Astron.) ; Couratin, Claire (Caen U.) ; Fabian, Xavier (Caen U.) ; Finlay, Paul (KU Leuven, Dept. Phys. Astron.) ; Flechard, Xavier (Caen U.) ; Friedag, Peter (Munster U. ; U. Munster) et al.
Weak interactions are described by the Standard Model which uses the basic assumption of a pure “V(ector)-A(xial vector)” character for the interaction. However, after more than half a century of model development and experimental testing of its fundamental ingredients, experimental limits for possible admixtures of scalar and/or tensor interactions are still as high as 7%.

Beta - neutrino correlation measurements are key in the research of physics beyond the Standard Model. In pure Fermi beta transitions, the beta-neutrino correlation coefficient, a βν, is sensitive to the presence of scalar currents. [...]

A compact radio frequency quadrupole for ion bunching in the WITCH experiment
/ Traykov, E. (Leuven U.) ; Beck, M. (Munster U.) ; Breitenfeldt, M. (Leuven U.) ; Delahaye, P. (CERN) ; De Leebeeck, V. (Leuven U.) ; Friedag, P. (Munster U.) ; Herlert, A. (CERN) ; Geeraert, N. (Leuven U.) ; Heirman, W. (Leuven U.) ; Lonne, P.I. (Bergen U.) et al.
During the last several years the WITCH (Weak Interaction Trap for CHarged particles) experimental setup at ISOLDE has undergone various upgrades aiming at improvement of general performance. An essential innovation, a compact Radio Frequency Quadrupole (RFQ) ion cooler and buncher device, was designed and successfully commissioned as a part of the off-line tuning system of WITCH. [...]

The standard model of the electroweak interaction describes beta-decay in the well-known V-A form. Nevertheless, the most general Hamiltonian of a beta-decay includes also other possible interaction types, e.g. [...]
