IRIS è la piattaforma adottata dall’Università degli Studi di Udine per gestire l’archivio aperto dei prodotti della ricerca. L’archivio contiene articoli, contributi in volume, monografie, interventi pubblicati in atti di convegno, Tesi di dottorato e altri materiali.
EnglishWe have searched in pp¯ collisions at √s=1.8TeV for events with three charged leptons and missing transverse energy. In the minimal supersymmetric standard model, we expect trilepton events from chargino-neutralino (χ̃±1χ̃02) pair production, with subsequent decay into leptons. We observe no candidate e+e−e±, e+e−μ±, e±μ+μ−, or μ+μ−μ± events in 106pb−1 integrated luminosity. We present limits on the sum of the branching ratios times cross section for the four channels: σχ̃±1χ̃02B(χ̃±1χ̃02→3ℓ+X)<0.34pb, Mχ̃±1>81.5GeV/c2, and Mχ̃02>82.2GeV/c2 for tanβ=2, μ=−600GeV/c2, and Mq̃=Mg̃.

| Abstract: | We have searched in pp¯ collisions at √s=1.8TeV for events with three charged leptons and missing transverse energy. In the minimal supersymmetric standard model, we expect trilepton events from chargino-neutralino (χ̃±1χ̃02) pair production, with subsequent decay into leptons. We observe no candidate e+e−e±, e+e−μ±, e±μ+μ−, or μ+μ−μ± events in 106pb−1 integrated luminosity. We present limits on the sum of the branching ratios times cross section for the four channels: σχ̃±1χ̃02B(χ̃±1χ̃02→3ℓ+X)<0.34pb, Mχ̃±1>81.5GeV/c2, and Mχ̃02>82.2GeV/c2 for tanβ=2, μ=−600GeV/c2, and Mq̃=Mg̃. |
