We argue that in asymptotically free non-Abelian gauge theories possessing the phenomenon of dynamical mass generation the beta function is negative up to a value of the coupling constant that corresponds to a non-trivial ...

We propose a technicolor model where, as a consequence of a hard asymptotic behavior for dynamically generated masses, effects of flavor changing neutral currents are highly suppressed and pseudo-Goldstone boson masses are ...

We study chiral symmetry breaking in QCD-like gauge theories introducing a confining effective propagator, as proposed recently by Cornwall, and considering the effect of dynamical gauge boson mass generation. The effective ...

In this work we study the dynamical generation of mass in the massless N = 1 Wess-Zumino model in a three-dimensional spacetime. Using the tadpole method to compute the effective potential, we observe that supersymmetry ...

We discuss some phenomenological applications of an infrared finite gluon propagator characterized by a dynamically generated gluon mass. In particular we compute the effect of the dynamical gluon mass on pp and ${\bar{p}}p$ ...

We use the QCD pomeron model proposed by Landshoff and Nachtmann to compute the differential and the total cross-sections for pp scattering in order to discuss a QCD-based approach to the proton form factor. This model is ...
