“…L and λ 2 R terms in the scalar leptoquark contribution to (g − 2) e have been calculated in detail in [76,75,15]. Djouadi, Kohler, Spira and Tuta [76], and Morris [74] also calculate the contribution proportional to λ L λ R . These should be closely related to F V and F A ; if one set m i = m f = m e in the final result for F V , one ought to get e(g − 2) e = F V .…”

“…It has been proposed that the extra D-terms could also solve the tachyon problems encountered in anomaly mediated SUSY breaking scenarios [97], while the inclusion of appropriate family symmetries could provide an explanation for the hierarchy of fermion masses and mixings [23,24,98,99]. Many further implications of these models have also been considered, including for EWSB [34,37,38,[100][101][102][103], neutrino physics [32,104], leptogenesis [18,19] and EW baryogenesis [105,106], the muon anomalous magnetic moment [107,108], electric dipole moments [89,90], lepton flavor violating processes [91] and the possibility of CP-violation in the extended Higgs sector [109].…”

We investigate dark matter in a constrained E 6 inspired supersymmetric model with an exact custodial symmetry and compare with the CMSSM. The breakdown of E 6 leads to an additional U(1) N symmetry and a discrete matter parity. The custodial and matter symmetries imply there are two stable dark matter candidates, though one may be extremely light and contribute negligibly to the relic density. We demonstrate that a predominantly Higgsino, or mixed bino-Higgsino, neutralino can account for all of the relic abundance of dark matter, while fitting a 125 GeV SM-like Higgs and evading LHC limits on new states. However we show that the recent LUX 2016 limit on direct detection places severe constraints on the mixed bino-Higgsino scenarios that explain all of the dark matter. Nonetheless we still reveal interesting scenarios where the gluino, neutralino and chargino are light and discoverable at the LHC, but the full relic abundance is not accounted for. At the same time we also show that there is a huge volume of parameter space, with a predominantly Higgsino dark matter candidate that explains all the relic abundance, that will be discoverable with XENON1T. Finally we demonstrate that for the E 6 inspired model the exotic leptoquarks could still be light and within range of future LHC searches.

“…Collider signatures associated with the exotic quarks and squarks have been considered in [30]. Previously, the implications of E 6 inspired SUSY models with an additional U(1) gauge symmetry have been studied for electroweak symmetry breaking (EWSB) [31][32][33][34][35][36][37], neutrino physics [38,39], leptogenesis [40,41], electroweak (EW) baryogenesis [42,43], the muon anomalous magnetic moment [44,45], the electric dipole moment of the electron [46] and of the tau lepton [47], for lepton flavor violating processes like µ → eγ [48] and for CP-violation in the Higgs sector [49]. The neutralino sector in E 6 inspired SUSY models was analysed in [36,[46][47][48][50][51][52][53][54][55][56][57].…”

In U(1) extensions of the Minimal Supersymmetric extension of the Standard Model there is a simple mechanism that leads to a heavy Z boson with a mass which is substantially larger than the supersymmetry breaking scale. This mechanism may also result in a pseudoscalar state that is light enough for decays of the 125 GeV Standard Model-like Higgs boson into a pair of such pseudoscalars to be kinematically allowed. We study these decays within E 6 inspired supersymmetric models with an exact custodial symmetry that forbids tree-level flavor-changing transitions and the most dangerous baryon and lepton number violating operators. We argue that the branching ratio of the lightest Higgs boson decays into a pair of the light pseudoscalar states may not be negligibly small.
