Theta dependence in Holographic QCD
Lorenzo Bartolini, Francesco Bigazzi, Stefano Bolognesi +2
We study the effects of the CP-breaking topological -term in the large QCD model by Witten, Sakai and Sugimoto with degenerate light flavors. We first compute the gr…
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…
Large-N CP(N-1) sigma model on a finite interval: physical boundary effects
Stefano Bolognesi, Kenichi Konishi, Keisuke Ohashi
We analyze the two-dimensional CP(N-1) sigma model defined on a finite space interval L, with various boundary conditions, in the large N limit. With the Dirichlet boundary conditi…
String pair production in non homogeneous backgrounds
Stefano Bolognesi, Eliezer Rabinovici, Gianni Tallarita
We consider string pair production in non homogeneous electric backgrounds. We study several particular configurations which can be addressed with the Euclidean world-sheet instant…
