Space-time symmetries and the Yang-Mills gradient flow
Luigi Del Debbio, Agostino Patella, Antonio Rago
The recent introduction of the gradient flow has provided a new tool to probe the dynamics of quantum field theories. The latest developments have shown how to use the gradient flo…
Mass corrections in string theory and lattice field theory
Luigi Del Debbio, Eoin Kerrane, Rodolfo Russo
Kaluza-Klein compactifications of higher dimensional Yang-Mills theories contain a number of four dimensional scalars corresponding to the internal components of the gauge field. W…
SU(N) gauge theories in the presence of a topological term
Luigi Del Debbio, Haralambos Panagopoulos, Ettore Vicari
We review recent results on the theta dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the CP-violatin…
The spectrum of SU(N) gauge theories at nonzero theta
Luigi Del Debbio, Gian Mario Manca, Haralambos Panagopoulos +2
We study the theta dependence of the spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the topological term in the Lagrangian, for N>=3 and in th…
Theta-dependence of the spectrum of SU(N) gauge theories
Luigi Del Debbio, Gian Mario Manca, Haralambos Panagopoulos +2
We study the theta dependence of the spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the topological term in the Lagrangian, for N>=3 and in th…
k-string tensions in the 4-d SU(N)-inspired dual Abelian-Higgs-type theory
Dmitri Antonov, Luigi Del Debbio, Dietmar Ebert
The k-string tensions are explored in the 4-d -invariant dual Abelian-Higgs-type theory. In the London limit of this theory, the Casimir scaling is found in the appro…
