Impact of slepton generation mixing on the search for sneutrinos 7 Lepton flavour violation in sneutrino production and decays in the general MSSM 0 0 K. Hidaka 2 t Department of Physics, Tokyo Gakugei University, Koganei, Tokyo 184–8501, Japan c O 2 Abstract. We perform a systematic study of sneutrino production and decays in the Minimal 1 Supersymmetric Standard Model (MSSM) with slepton generation mixing. We study bosonic decays − + + ˜ like ν˜ → ℓ + W /H as well as fermionic ones. We show that the effect of slepton generation ] mixing on the sneutrino production and decays can be quite large in a significant part of the MSSM h parameter space despite the very strong experimental limits on lepton flavour violating processes. p - This could have an important impact on the search for sneutrinos and the determination of the p MSSM parameters at future colliders, such as LHC, ILC, CLIC and muon collider. e h PACS. 12.15.Ji Applications of electroweak models to specific processes [ 2 1 Introduction + m2 δαβ , v ℓα 7 2 2 2 2 2 8 Systematic studies of decays of sneutrinos, the super- MRR,αβ = ME,αβ − mZ cos(2β) sin θW δαβ + mℓα δαβ , 0 symmetric (SUSY) partners of neutrinos, in the Min- M 2 = v A − m ∗ tan βδ .
