A. E. Faraggi, S. Groot Nibbelink, M. Hurtado-Heredia

摘要:

旋量-向量对偶的印记已经在各种弦结构中被发现。它们通常是通过改变底层弦配分函数中的某些自由一般GSO相位而引起的。本文证明了六维旋量-矢量对偶性受一个基本的有效场论相容性条件的约束,即任何六维低能理论必须没有不可约SO(2N)反常.方面的旋量矢量对偶性进行了分析,在四个六维自由费米子模型的区别是由两个广义GSO阶段。此外,旋量和矢量的数量上的约束被确认的通用频谱可能会发生在K3线束紧凑化的杂种优势E8 xE 8串。

英文摘要:

Imprints of spinor-vector dualities have been uncovered in various string constructions. They are typically induced by changing certain free general GSO phases in the underlying string partition functions. This paper shows that spinor-vector dualities in six dimensions are constrained by a fundamental effective field theory consistency condition, namely that any six dimensional low energy theory must be free of irreducible SO(2N) anomalies. Aspects of spinor-vector dualities are analysed in four six-dimensional free fermionic models which are distinguished by two generalised GSO phases. In addition, the constraint on the number of spinors and vectors is confirmed on generic spectra which may occur in K3 line bundle compactifications of the heterotic E8xE8 string.
