Heavy Axion from a Confining Mirror GUT
Giacomo Cacciapaglia, Csaba Csáki, Teng Ma
We propose a new framework for solving the strong CP problem via a heavy axion, using mirror symmetry and grand unification. The mirror GUT sector remains unbroken and dynamically…
Non-Abelian and Type-A Conformal Anomalies from Euler Descent
Gleb Aminov, Csaba Csáki, Ofri Telem +1
We classify the non-Abelian anomaly of the Euclidean conformal group in dimensions via Stora-Zumino descent from its Euler invariant polynomial in dimensio…
Ultralight Dilatonic Dark Matter
Abhishek Banerjee, Csaba Csáki, Michael Geller +2
The dilaton, a pseudo-Nambu-Goldstone boson (pNGB) of broken scale invariance, is an appealing ultralight dark matter (DM) candidate. Its mass is protected by conformal invariance…
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 holograph…
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 fr…
Strong CP from a Hidden Chiral Condensate
Csaba Csáki, Samuel Homiller, Taewook Youn
Models which solve the strong CP problem by employing discrete spacetime symmetries generically suffer fine-tuning and quality problems. We demonstrate that these issues are greatl…
