Gauge Dependence in the Nonlinearly Realized Massive SU(2) Gauge Theory
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
The implementation of the 't Hooft alpha-gauge in the symmetrically subtracted massive gauge theory based on the nonlinearly realized SU(2) gauge group is discussed. The gauge inde…
A Massive Yang-Mills Theory based on the Nonlinearly Realized Gauge Group
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
We propose a subtraction scheme for a massive Yang-Mills theory realized via a nonlinear representation of the gauge group (here SU(2)). It is based on the subtraction of the poles…
Further Comments on the Symmetric Subtraction of the Nonlinear Sigma Model
Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri
Recently a perturbative theory has been constructed, starting from the Feynman rules of the nonlinear sigma model at the tree level in the presence of an external vector source cou…
