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…
Search for Higgs bosons decaying to WW in e+e- collisions at LEP
ALEPH collaboration
A search for Higgs bosons produced in association with a fermion pair, and decaying to WW, is performed with the data collected by the ALEPH detector at centre-of-mass energies ran…
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…
