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…
Fermion pair production in e+e- collisions at 189-209 GeV and constraints on physics beyond the Standard Model
The ALEPH Collaboration
Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 G…
Measurement of the W boson mass and width in e+e- collisions at LEP
The ALEPH Collaboration
The mass of the W boson is determined from the direct reconstruction of its decays into purely hadronic and semi-leptonic events in e+e- collisions at LEP. The data sample correspo…
Test of Colour Reconnection Models using Three-Jet Events in Hadronic Z Decays
ALEPH collaboration
Hadronic Z decays into three jets are used to test QCD models of colour reconnection (CR). A sensitive quantity is the rate of gluon jets with a gap in the particle rapidity distri…
Branching ratios and spectral functions of tau decays: final ALEPH measurements and physics implications
the ALEPH Collaboration
The full LEP-1 data set collected with the ALEPH detector at the pole during 1991-1995 is analysed in order to measure the decay branching fractions. Extensive systematic s…
Absolute Lower Limits on the Masses of Selectrons and Sneutrinos in the MSSM
ALEPH Collaboration
The results of searches for selectrons, charginos and neutralinos performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies up to 209 GeV are interp…
