与EFT字符串的大字段距离

Large Field Distances from EFT strings

Stefano Lanza, Fernando Marchesano, Luca Martucci, Irene Valenzuela

摘要:

在任何相容的量子引力的有效场论中,无限场距离的极限预期会导致EFT击穿,因为出现了无限的光态塔,正如距离猜想所预测的那样。我们回顾了远轴弦猜想,它提出任何四维EFT无限场距离极限可以实现为基本轴弦的RG流。RG流可以根据这种弦的4d反作用来理解,并且意味着它朝着所述极限变得无张力。这种性质被理解为实现精确轴对称的屏蔽机制,它意味着EFT以再现距离猜想的方式被打破。受弦论数据的启发,我们进一步提出了积分标度猜想,它提供了一个特定的弦张力和无限状态塔的EFT最大截止集之间的关系。

英文摘要:

In any consistent effective field theory of quantum gravity limits of infinite field distance are expected to lead to the EFT breakdown due to the appearance of an infinite tower of light states, as predicted by the Distance Conjecture. We review the Distant Axionic String Conjecture, which proposes that any 4d EFT infinite-field-distance limit can be realized as an RG flow of a fundamental axionic string. The RG flow can be understood in terms of the 4d backreaction of such a string, and implies that it becomes tensionless towards the said limit. This property is understood as a shielding mechanism towards realizing an exact axionic symmetry, and it implies the breakdown of the EFT in a way that reproduces the Distance Conjecture. Motivated by string theory data we further propose the Integral Scaling Conjecture, which provides a specific relation between the string tension and the EFT maximal cut-off set by the infinite tower of states.
