Tidskriftsartikel (refereegranskat)abstract
- The tau polarisation has been studied with the e(+)e(-) --> tau(+)tau(-) data collected by the DELPHI detector at LEP in 1993, 1994 and 1995 around the Z resonance firstly through the exclusive decay channels ev (v) over bar, mu v (v) over bar, pi v, rho

Tidskriftsartikel (refereegranskat)abstract
- This paper describes a measurement of the Michel parameters, eta, rho, xi, xi delta, and the average v(tau) helicity, h(nu tau), in tau lepton decays together with the first measurement of the tensor coupling in the weak charged current. The tau(+)tau(-)

Cross-sections and leptonic forward-backward asymmetries from the Z(0) running of LEP

Tidskriftsartikel (refereegranskat)abstract
- During 1993 and 1995 LEP was run at 3 energies near the Z(0) peak in order to give improved measurements of the mass and width of the resonance. During 1994, LEP operated only at the Z(0) peak. In total DELPHI accumulated data corresponding to an integrat

Tidskriftsartikel (refereegranskat)abstract
- The probability P(c --> D*(+)) that a charm quark fragments into a D*+ meson and the c --> l(+) semileptonic branching fraction were measured in Z(0) decay into c (c) over bar events. From the analysis of 3.5 Million Z(0) events collected from 1992 to 199
