Production of Ds** mesons in hadronic Z decays
ALEPH Collaboration
The production rates of the orbitally excited Ds** mesons, Ds1 and Ds2*, are measured with the 4.1 million hadronic Z decays recorded by the ALEPH detector during 1991--1995. The D…
Measurement of Ab_FB using inclusive b-hadron decays
ALEPH Collaboration
Based on a sample of four million events collected by ALEPH from 1991 to 1995, a measurement of the forward-backward asymmetry in Z -> b-barb decays using inclusive final states is…
Study of the fragmentation of b quarks into B mesons at the Z peak
ALEPH Collaboration
The fragmentation of b quarks into B mesons is studied with four million hadronic Z decays collected by the ALEPH experiment during the years 1991-1995. A semi-exclusive reconstruc…
New results on alpha_s and optimized scales
S. Bravo
A summary of the latest alpha_s results at LEP1 and LEP2 from event-shape predictions at Order(alpha2_s) + NLLA is presented. Later these are compared to measurements obtained usin…
