Non-derivative Axionic Couplings to Nucleons at large and small N
Francesco Bigazzi, Aldo L. Cotrone, Matti Järvinen +1
Among the possible CP-odd couplings of the axion to ordinary matter, the most relevant ones for phenomenology are the Yukawa couplings to nucleons. We analyze such non-derivative c…
Axion RG flows and the holographic dynamics of instanton densities
Yuta Hamada, Elias Kiritsis, Francesco Nitti +1
Axionic holographic RG flow solutions are studied in the context of general Einstein-Axion-Dilaton theories. A non-trivial axion profile is dual to the (non-perturbative) running o…
Brane cosmology and the self-tuning of the cosmological constant
A. Amariti, C. Charmousis, D. Forcella +2
The cosmology of branes undergoing the self-tuning mechanism of the cosmological constant is considered. The equations and matching conditions are derived in several coordinate sys…
Euclidean Wormholes and Holography
Panos Betzios, Elias Kiritsis, Olga Papadoulaki
Asymptotically AdS wormhole solutions are considered in the context of holography. Correlation functions of local operators on distinct boundaries are studied. It is found that suc…
