Search for neutral Higgs bosons decaying into four taus at LEP2
ALEPH Collaboration, S. Schael, R. Barate +258
A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb-1 of data collected by the ALEP…
Search for charginos nearly mass degenerate with the lightest neutralino in e+e- collisions at centre-of-mass energies up to 209GeV
ALEPH Collaboration
A search for charginos nearly mass degenerate with the lightest neutralino is performed with the data collected by the ALEPH detector at LEP, at centre-of-mass energies between 189…
Search for the glueball candidates f0(1500) and fJ(1710) in gamma gamma collisions
ALEPH Collaboration
Data taken with the ALEPH detector at LEP1 have been used to search for gamma gamma production of the glueball candidates f0(1500) and fJ(1710) via their decay to pi+pi-. No signal…
Monitoring the Stability of the ALEPH Vertex Detector
G. Sguazzoni
The ALEPH Silicon Vertex Detector features an optical fibre laser system to monitor its mechanical stability. The operating principle and the general performance of the laser syste…
