Search for neutral MSSM Higgs bosons at LEP
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric standard model (MSSM). The data of the fourExpand
Electroweak measurements in electron positron collisions at W-boson-pair energies at LEP
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a totalExpand
Performance of the Aleph Detector At Lep
The performance of the ALEPH detector at the LEP e+e− collider is reviewed. The accuracy of the tracking detectors to measure the impact parameter and momentum of charged tracks is specified.Expand
Branching ratios and spectral functions of tau decays: Final ALEPH measurements and physics implications
The full LEP-1 data set collected with the ALEPH detector at the Z pole during 1991-1995 is analysed in order to measure the tau decay branching fractions. The analysis follows the global method usedExpand
ALEPH: A detector for electron-positron annihilations at LEP
Process-centred Software Engineering Environments (PSEE) are the most recent generation of environments supporting software development activities. Most of PSEE are based on mechanisms promotingExpand
A measurement of the inclusive b -> s gamma branching ratio
The flavour changing neutral current decay b --> s gamma has been detected in hadronic Z decays collected by ALEPH at LEP. The signal is isolated in lifetime-tagged b (b) over bar events by theExpand
Studies of quantum chromodynamics with the ALEPH detector
Abstract Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative andExpand
Fermion pair production in e+e- collisions at 189–209 GeV and constraints on physics beyond the standard model
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 GeV at LEP, measuredExpand

TLDR
The notion of group entropy enables the unification and generaliztion of many different definitions of entropy known in the literature, such as those of Boltzmann-Gibbs, Tsallis, Abe, and Kaniadakis, and generalizations of the Kullback-Leibler divergence are proposed. Expand
Study of the fragmentation of b quarks into B mesons at the Z peak
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 reconstruction of B->l nuExpand
