T^6/Z_3定向折叠上的D-膜瞬子

D-brane Instantons on the T^6/Z_3 orientifold

Massimo Bianchi, Francesco Fucito, Jose F. Morales

摘要:

我们给出了D3膜上Z3-定向折叠奇点上规范理论的规范超势和弦瞬子超势的详细微观推导。规范瞬子是由D(-1)-膜产生的,在具有三代双基本反对称物质的有效N=1规范理论中,规范瞬子导致了类似于Affleck,Dine和Seiberg(ADS)的超势。弦瞬子效应是由T^6/ \Z_3上缠绕四圈的欧几里得ED 3膜产生的。它们在一种情况下产生马约拉纳质量,在另一种情况下产生不可重整化的超势。最后,我们确定了在N=1规范理论中伴随、基本、对称和反对称手征物质产生类ADS超势的条件。

英文摘要:

We give a detailed microscopic derivation of gauge and stringy instanton generated superpotentials for gauge theories living on D3-branes at Z_3-orientifold singularities. Gauge instantons are generated by D(-1)-branes and lead to Affleck, Dine and Seiberg (ADS) like superpotentials in the effective N=1 gauge theories with three generations of bifundamental and anti/symmetric matter. Stringy instanton effects are generated by Euclidean ED3-branes wrapping four-cycles on T^6/\Z_3. They give rise to Majorana masses in one case and non-renormalizable superpotentials for the other cases. Finally we determine the conditions under which ADS like superpotentials are generated in N=1 gauge theories with adjoints, fundamentals, symmetric and antisymmetric chiral matter.
