IIB型超对称磁通计

Type IIB Supersymmetric Flux Vacua

Ching-Ming Chen, Shan Hu, Tianjun Li, Dimitri V. Nanopoulos

摘要:

在具有一般通量紧化的IIB型环面T^6定向折叠上,我们猜想在一般超对称Minkowski真空中,如果模被适当地稳定化,则对7-膜和D3-膜蝌蚪的通量贡献中至少有一个是正的,并且蝌蚪抵消条件不能放松。为了研究超对称闵可夫斯基流真空,我们对流进行了合理的简化,并讨论了相应的超势。我们发现,我们不能同时有所有的模的正实部和负/零通量的贡献,所有的七膜和D3膜蝌蚪。因此,我们不能用放松的蝌蚪相消条件来构造现实的磁链模型。在研究超对称AdS真空时,我们得到了七膜和D3膜蝌蚪相消条件的通量模型,并给出了一个半真实的Pati-Salam模型及其粒子谱.从AdS真空到Minkowski/dS真空的提升仍然是环形定向褶皱上通量模型构建的一个巨大挑战。

英文摘要:

On the Type IIB toroidal T^6 orientifolds with generic flux compactifications, we conjecture that in generic supsersymmetric Minkowski vacua, at least one of the flux contributions to the seven-brane and D3-brane tadpoles is positive if the moduli are stabilized properly, and then the tadpole cancellation conditions can not be relaxed. To study the supsersymmetric Minkowski flux vacua, we simplify the fluxes reasonably and discuss the corresponding superpotential. We show that we can not have simultaneously the positive real parts of all the moduli and the negative/zero flux contributions to all the seven-brane and D3-brane tadpoles. Therefore, we can not construct realistic flux models with the relaxed tadpole cancellation conditions. When studying the supsersymmetric AdS vacua, we obtain flux models with the seven-brane and D3-brane tadpole cancellation conditions relaxed elegantly, and we present a semi-realistic Pati-Salam model as well as its particle spectrum. The lifting from the AdS vacua to the Minkowski/dS vacua remains a great challenge in flux model buildings on toroidal orientifolds.
