“…it the lightest sneutrino ν 1 can also service as a good candidate [5][6][7][8][9][10][11][12][13][14][15]. In the MSSM ν 1 is a fully electroweak complex scalar ν L , and thus Z boson mediates so large DM-nucleon recoil [16] that it has been excluded by the DM direct detection experiments like LUX [17] (given a correct DM relic density).…”

“…The effective coupling constants g L/R can be expressed in terms of the gauge/Yukawa coupling constants and the mixing angles in the stop and chargino sectors, etc. For instance, in the supersymmetric inverse seesaw models the sneutrino LSP DM may be a highly complex scalar, thus dominated by the singlets [14]. Then we can further simplify the model by working in the Higgsino-limit with…”

“…There are previous works taking advantage of the leptonic nature to explore relevant signatures. For example, based on the supersymmetric inverse seesaw [6,[9][10][11][12][13][14][15], ref. [21] studied the trilepton plus missing E T signature from C ± 1 χ 2 production.…”

Abstract:The current searches of supersymmetry (SUSY) are based on the neutralino lightest sparticle (LSP). In this article we instead focus on SUSY with sneutrino LSP. It is well motivated in many contexts, especially in which sneutrino services as a dark matter candidate. We first develop a simplified model, which contains the stop, chargino/neutralino and sneutrino, to describe the LHC phenomenologies of a large class of models with sneutrino LSP. Then we investigate bounds on the model using the SUSY searches at the 8 TeV LHC. Strong exclusion limits are derived, e.g., masses of stop and chargino can be excluded up to about 900 GeV and 550 GeV, respectively. We also propose optimizations for some searches without turning to higher energy and luminosity.

“…The most relevant process for our sneutrino DM is through the Z-boson exchange even this is not LH but RH [9,10], in contrast with most of other RH sneutrino DM models where the Higgs bosons exchange is dominant [42][43][44][45][46][47][48][49][50]. The DM-DM-Z vertex is induced by one-loop digram involving neutrinophilic Higgs boson.…”

We study a supersymmetric neutrinophilic Higgs model with large neutrino Yukawa couplings where neutrinos are Dirac particles and the lightest right-handed (RH) sneutrino is the lightest supersymmetric particle (LSP) as a dark matter candidate. Neutrinophilic Higgs bosons need to be rather heavy by the precise determination of the muon decay width and dark radiation constraints for large Yukawa couplings. From the Large Hadron Collider constraints, neutrinophilic Higgsino mass need to be heavier than several hundred GeV or close to the RH sneutrino LSP mass. The latter case is interesting because the muon anomalous magnetic dipole moment can be explained with a relatively large lightest neutrino mass, if RH sneutrino mixings are appropriately fine tuned in order to avoid stringent lepton flavor violation constraints. Dark matter is explained by asymmetric RH sneutrino dark matter in the favoured region by the muon anomalous magnetic dipole moment. In other regions, RH sneutrino could be an usual WIMP dark matter.

“…In the present work, we revisit the consequences of the inverse seesaw model for the lightest CP-even Higgs boson mass [23,24]. We find parameter regions in which the one-loop corrections to the light Higgs mass can be very significant, leading to an increase of O(10) GeV, for the neutrino Yukawa coupling larger than about 0.2.…”

We compute the one loop corrections to the CP-even Higgs mass matrix in the supersymmetric inverse seesaw model to single out the different cases where the radiative corrections from the neutrino sector could become important. It is found that there could be a significant enhancement in the Higgs mass even for Dirac neutrino masses of O(30) GeV if the left-handed sneutrino soft mass is comparable or larger than the right-handed neutrino mass. In the case where right-handed neutrino masses are significantly larger than the supersymmetry breaking scale, the corrections can utmost account to an upward shift of 3 GeV. For very heavy multi TeV sneutrinos, the corrections replicate the stop corrections at 1-loop. We further show that general gauge mediation with inverse seesaw model naturally accommodates a 125 GeV Higgs with TeV scale stops.
