The Minimal Supersymmetric Extension of the Standard Model (MSSM) is able to explain the current data from neutrino physics. Unfortunately Split Supersymmetry as low energy approximation of this theory fails to generate a solar square mass difference, including after the addition of bilinear R-Parity Violation. In this work, it is shown how one can derive an effective low energy theory from the MSSM in the spirit of Split Supersymmetry, which has the potential of explaining the neutrino phenomenology. This is achieved by going beyond leading order in the process of integrating out heavy scalars from the original theory, which results in non-renormalizable operators in the effective low energy theory. It is found that in particular a d=8 operator is crucial for the generation of the neutrino mass differences.

Non-renormalizable operators for solar neutrino mass generation in Split SuSy with bilinear R-parity violation

We study the Inert Higgs Doublet Model and its inert scalar Higgs <math id="M1"><mrow><mi>H</mi></mrow></math> as the only source for dark matter. It is found that three mass regions of the inert scalar Higgs can give the correct dark matter relic density. The low mass region (between 3 and 50 GeV) is ruled out. New direct dark matter detection experiments will probe the intermediate (between 60 and 100 GeV) and high (heavier than 550 GeV) mass regions. Collider experiments are advised to search for <math id="M2"><msup><mrow><mi>D</mi></mrow><mrow><mo>±</mo></mrow></msup><mo>→</mo><mi>H</mi><msup><mrow><mi>W</mi></mrow><mrow><mo>±</mo></mrow></msup></math> decay in the two jets plus missing energy channel.
