Measurement of the electron structure function F$\frac{e}{2}$ at LEP energies
DELPHI collaboration (343 authors); Abreu, P.; Andringa, S.; Anjos, N.; Castro, N.; De Angelis, A.; Espirito Santo, M.C.; Gonçalves, P.; Onofre, A.The hadronic part of the electron structure function F2e has been measured for the first time, using e+e− data collected by the DELPHI experiment at LEP, at centre-of-mass energies of s=91.2–209.5 GeV . The data analysis is simpler than that of the measurement of the photon structure function. The electron structure function F2e data are compared to predictions of phenomenological models based on the photon str...
Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energi...
ALEPH, DELPHI, L3, OPAL, LEP Electroweak collaboration (1644 authors); David, A.; Abreu, P.; Andringa, S.; Anjos, N.; Castro, N.; De Angelis, A.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 total luminosity of about 3 fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from 130 GeV to 209 GeV. Combining the published results of the four LEP experime...
Search for Charged Higgs bosons: Combined Results Using LEP Data
ALEPH, DELPHI, L3, OPAL, LEP collaboration (1216 authors); Abreu, P.; Andringa, S.; Anjos, N.; Castro, Nuno Filipe; De Angelis, A.; Espirito Santo, M.C.The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments are statistically combined. The results are interpreted within the 2HDM for Type I and Type II benchmark scenarios. No statistically significant excess has been observed when compared to the Standard Model background ...
