Measurements of BR (b -> tau- nubar_tau X) and BR (b -> tau- nubar_tau D*+- X) and Upper Limits on BR (B- -> tau- nubar_tau) and BR (b -> s nu nubar)
ALEPH Collaboration
Inclusive branching ratios involving b to tau transitions are measured in approximately four million hadronic Z decays collected by the ALEPH detector at LEP. The fully-inclusive b…
Study of the CP asymmetry of B0 -> J/psi K0S decays in ALEPH
ALEPH Collaboration
The decay B0 -> J/psi K0_S is reconstructed with J/psi -> e+ e- or mu+ mu- and K0_S -> pi+ pi-. From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candida…
Measurement of the Bbar0 and B- Meson Lifetimes
ALEPH Collaboration
The lifetimes of the Bbar0 and B- mesons are measured using a sample of about four million hadronic Z decays collected from 1991 to 1995 with the ALEPH detector at LEP. The data sa…
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…
Measurement of the e+e- -> ZZ production cross-section at centre-of-mass energies of 183 and 189GeV
ALEPH Collaboration
The ee -> ZZ cross section at sqrt(s)=182.7 and 188.6 GeV has been measured using the ALEPH detector. The analysis covers all of the visible ZZ final states and yields cross sectio…
