“…35 We have again made a convenient choice for the integration constant in s. 36 More generally, a holomorphic 1-form on a genus g curve of this type will have g free parameters, which is enough freedom to fix the A-periods but further imposing constraints on B-periods fixes the moduli. On the other hand, a harmonic 1-form on a genus g curve of this type will have 2g free parameters, which is enough freedom to fix all periods for arbitrary values of the moduli.…”

Nonsupersymmetric brane/antibrane configurations in type IIA and M theory

We study metastable nonsupersymmetric configurations in type IIA string theory, obtained by suspending D4-branes and D4-branes between holomorphically curved NS5's, which are related to those of hep-th/0610249 by T -duality. When the numbers of branes and antibranes are the same, we are able to obtain an exact M theory lift which can be used to reliably describe the vacuum configuration as a curved NS5 with dissolved RR flux for g s ≪ 1 and as a curved M5 for g s ≫ 1. When our weakly coupled description is reliable, it is related by T -duality to the deformed IIB geometry with flux of hep-th/0610249 with moduli exactly minimizing the potential derived therein using special geometry. Moreover, we can use a direct analysis of the action to argue that this agreement must also hold for the more general brane/antibrane configurations of hep-th/0610249. On the other hand, when our strongly coupled description is reliable, the M5 wraps a nonholomorphic minimal area curve that can exhibit quite different properties, suggesting that the residual structure remaining after spontaneous breaking of supersymmetry at tree level can be further broken by the effects of string interactions. Finally, we discuss the boundary condition issues raised in hep-th/0608157 for nonsupersymmetric IIA configurations, their implications for our setup, and their realization on the type IIB side.

“…Because such configurations do not correspond to true vacua, many of the difficulties associated with the construction of realistic models of supersymmetry-breaking can be avoided. As such, the ideas of [1] have already found wide phenomenological application [33,34,35,36,37,38,39,40,41].…”

“…There, the scalar potential is well approximated by 9) where V ISS is the global supersymmetric (as opposed to supergravity) scalar potential for the ISS sector. However, when computing the critical temperature, we will consider the expansion (2.9) to be valid at the origin of the field space as well.…”

We study the static phase structure of the ISS-KKLT model for moduli stabilisation and uplifting to a zero cosmological constant. Since the supersymmetry breaking sector and the moduli sector are only gravitationally coupled, we expect negligible quantum effects of the modulus upon the ISS sector, and the other way around. Under this assumption, we show that the ISS fields end up in the metastable vacua. The reason is not only that it is thermally favoured (second order phase transition) compared to the phase transition towards the supersymmetric vacua, but rather that the metastable vacua form before the supersymmetric ones. This nice feature is exclusively due to the presence of the KKLT sector. We also show that supergravity effects are negligible around the origin of the field space. Finally, we turn to the modulus sector and show that there is no destabilisation effect coming from the ISS sector.0

“…Note that ln (M p /m 3/2 ) ∼ O 8π 2 and compensate the loop suppression factors appeared in the anomaly mediated contributions. α = 1 is realized in the original KKLT-setup [28], but various rational values can be obtained in the similar setups [8,9,29,30]. An important fact is that α could be determined by rational parameters, such as the winding number of D-branes and the number of fluxes which generates moduli potential.…”

Abstract:We discuss effective models derived from a supersymmetric model whose mediation mechanism of supersymmetry (SUSY) breaking is namely mirage mediation. In this model, light higgsino mass, that is required by the natural realization of the electroweak scale, is achieved by the unification of the soft SUSY breaking parameters at the low scale. Besides, we find that extra Higgs fields are also possibly light in some cases. Then, the effective model is a two Higgs doublet model (2HDM) with higgsinos, and it is distinguishable with namely type-II 2HDM which is widely discussed. In this paper, we study the mass spectrum of SUSY particles and the extra Higgs fields, and summarize the phenomenology in the effective model. We survey the current experimental bounds from the LHC and the dark matter experiments as well as the flavor physics. Then, we point out the expected mass scale of the SUSY particles and reveal the future prospects for the direct and indirect searches. We also discuss the difference between our effective model and the 2HDM in the bottom-up approach.
