Axionic Strings, Domain Walls and Baryons
Francesco Bigazzi, Aldo L. Cotrone, Andrea Olzi
When axionic strings carry a global charge, domain walls bounded by such strings may not be allowed to decay completely. This happens in particular in some models where a composite…
Bubble Wall Velocity at Strong Coupling
Francesco Bigazzi, Alessio Caddeo, Tommaso Canneti +1
Using the holographic correspondence as a tool, we determine the steady-state velocity of expanding vacuum bubbles nucleated within chiral finite temperature first-order phase tran…
Dark Holograms and Gravitational Waves
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +1
Spectra of stochastic gravitational waves (GW) generated in cosmological first-order phase transitions are computed within strongly correlated theories with a dual holographic desc…
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…
Neutron electric dipole moment from gauge/string duality
Lorenzo Bartolini, Francesco Bigazzi, Stefano Bolognesi +2
We compute the electric dipole moment of nucleons in the large QCD model by Witten, Sakai and Sugimoto with degenerate massive flavors. Baryons in the model are insta…
