Gravitational Waves from Long Strings and Loops
Christos Litos, Sarunas Verner, Wei Xue +1
We compute the gravitational wave spectrum produced by a global cosmic string network in the scaling regime. The spectrum naturally divides at the string correlation length into in…

The Holographic QCD Axion in Five Dimensions
Csaba Csáki, Eric Kuflik, Wei Xue +1
We present a holographic construction of the QCD axion based on a warped 5D model. A key ingredient of our setup is the introduction of a bulk scalar field , which is holographi…

Angle and Axial Anomaly in Holographic QCD
Csaba Csáki, Eric Kuflik, Wei Xue +1
We present a bottom-up holographic description of the QCD -vacuum and the anomaly in five dimensions. The multi-branched -vacuum structure emerges geometrically from…
