D=10时Anomaly相消理论的分析

An Analysis of Anomaly Cancellation for Theories in D=10

Andrea Antonelli

摘要:

我们证明了D=10 N=1的SUGRA与D=10 N=1的SYM耦合的沼泽地只由U(1)^496和E_8 x U(1)^248构成。考虑到这一目标,我们回顾了异常的经典和特殊的群体,检索跟踪身份的曲率为每一类的第六权力。我们扩展这个想法的低维组,其中的第六次幂的轨迹是已知的因式分解,我们检索这样的因式分解。我们获得了各个低维群及其组合的总反常多项式,最后我们研究了它们的非因式分解,使得U(1)^496和E_8 xU(1)^248被非平凡地证明是D=10中唯一允许的无反常理论。使用的方法检查的因式分解的规范理论,我们检索的格林-施瓦茨项的两个理论填充沼泽地。

英文摘要:

We prove that the swampland for D=10 N=1 SUGRA coupled to D=10 N=1 SYM is only populated by U(1)^496 and E_8 x U(1)^248. With this goal in mind, we review the anomalies for classical and exceptional groups, retrieving trace identities up to the sixth power of the curvature for each class of groups. We expand this idea for low-dimensional groups, for which the trace of the sixth power is known to factorize, and we retrieve such factorization. We obtain the total anomaly polynomials for individual low dimensional groups and combinations of them and finally we investigate their non-factorization, in such a way that U(1)^496and E_8 xU(1)^248 are non-trivially shown to be the only anomaly-free theories allowed in D=10. Using the method developed for checking the factorization of gauge theories, we retrieve the Green-Schwarz terms for the two theories populating the swampland.
