Search for scalar leptons in e+e- collisions

Search for pair production of sleptons have been performed using the data collected by the ALEPH detector at LEP in the year 2000. The centre-of-mass energy ranges from 204 to 209 GeV, corresponding to an integrated luminosity of 207.3 pb-1. No evidence for the production of these particles was foun...

Sumario:Search for pair production of sleptons have been performed using the data collected by the ALEPH detector at LEP in the year 2000. The centre-of-mass energy ranges from 204 to 209 GeV, corresponding to an integrated luminosity of 207.3 pb-1. No evidence for the production of these particles was found. The number of candidates observed is consistent with the background expected from four-fermion processes and gamma-gamma interactions. Improved mass limits at 95% C.L. are reported.
