On the Spectrum of Lattice Massive SU(2) Yang-Mills
Ruggero Ferrari
On the basis of extended simulations we provide some results concerning the spectrum of Massive SU(2) Yang-Mills on the lattice. We study the "time" correlator of local gauge invar…
Nonlinear Realization of the SU(5) Georgi-Glashow Model
Daniele Bettinelli, Ruggero Ferrari, Alessandro Sanzeni
The formulation of a grand unified field theory based on the nonlinearly realized SU(5) gauge group is presented. The tree-level action is constructed by requiring invariance under…
Metamorphosis versus Decoupling in Nonabelian Gauge Theories at Very High Energies
Ruggero Ferrari
In the present paper we study the limit of zero mass in nonabelian gauge theories both with Higgs mechanism and in the nonlinear realization of the gauge group (Stueckelberg mass).…
Of Higgs, Unitarity and other Questions
D. Bettinelli, R. Ferrari, A. Quadri
On the verge of conclusive checks on the Standard Model by the LHC, we discuss some of the basic assumptions. The reason for this analysis stems from a recent proposal of an Electr…
The Electroweak Model based on the Nonlinearly realized Gauge Group. Theoretical Foundations and Phenomenological Prospects
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
A consistent strategy for the subtraction of the divergences in the nonlinearly realized Electroweak Model in the loop expansion is presented. No Higgs field enters into the pertur…
The SU(2) X U(1) Electroweak Model based on the Nonlinearly Realized Gauge Group
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
The electroweak model is formulated on the nonlinearly realized gauge group SU(2) X U(1). This implies that in perturbation theory no Higgs field is present. The paper provides the…
