Nonlinearly Realized Gauge Theories for LHC Physics
D. Bettinelli, D. Binosi, A. Quadri
We consider a minimal nonlinearly realized electroweak theory where mass generation happens à la Stueckelberg. Deformation of the nonlinearly realized gauge symmetry is controlled…
The Stueckelberg Mechanism in the presence of Physical Scalar Resonances
D. Bettinelli, A. Quadri
We show that it is possible to accommodate physical scalar resonances within a minimal nonlinearly realized electroweak theory in a way compatible with a natural Hopf algebra selec…
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…
Heavy top renormalon contribution to fermion propagators
D. Bettinelli, J. J. van der Bij
We study resummed perturbative contributions due to a heavy top-quark. These renormalon contributions are evaluated for fermion propagators. Results for the top-quark width are giv…
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…
Resummed corrections to the ρparameter in the complex mass scheme
D. Bettinelli, J. J. van der Bij
We present all order results for the heavy top corrections to the ρparameter in the complex mass scheme. We derive translation formulas between the complex mass and the on-shell sc…
