Deuteron electric dipole moment from holographic QCD
Lorenzo Bartolini, Stefano Bolognesi, Sven Bjarke Gudnason
We compute the electric dipole moment (EDM) of the deuteron in the holographic QCD model of Witten-Sakai-Sugimoto. Previously, the leading contribution to the EDM of nucleons was c…
Gauging 1-form center symmetries in simple gauge theories
Stefano Bolognesi, Kenichi Konishi, Andrea Luzio
Consequences of gauging exact center symmetries in several simple gauge theories, where is a divisor of , are investigated. Models discussed include: the $SU…
Vortons with Abelian and non-Abelian currents and their stability
Gianni Tallarita, Adam Peterson, Stefano Bolognesi +1
We explore vorton solutions in the Witten's model for cosmic strings and in a modified version obtained by introducing a triplet of non-Abeli…
Dynamics and symmetries in chiral gauge theories
Stefano Bolognesi, Kenichi Konishi
Dynamics and symmetry realization in various chiral gauge theories in four dimensions are investigated, generalizing a recent work by M. Shifman and the present authors, by relying…
Large- sigma model on a Euclidean torus: uniqueness and stability of the vacuum
Stefano Bolognesi, Sven Bjarke Gudnason, Kenichi Konishi +1
In this paper we examine analytically the large- gap equation and its solution for the sigma model defined on a Euclidean spacetime torus of arbitrary s…
