Hamiltonian study of the asymptotic symmetries of gauge theories
Roberto Tanzi
Asymptotic symmetries are a general and important feature of theories with long-ranging fields, such as gravity, electromagnetism, and Yang-Mills. They appear in the formalism once…

Asymptotic symmetries of scalar electrodynamics and of the abelian Higgs model in Hamiltonian formulation
Roberto Tanzi, Domenico Giulini
We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux…

Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation
Roberto Tanzi, Domenico Giulini
We investigate the asymptotic symmetry group of the free SU(N)-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who succ…
