Exponentially Modified QCD Coupling
Gorazd Cvetic, Cristian Valenzuela
We present a specific class of models for an infrared-finite analytic QCD coupling, such that at large space-like energy scales the coupling differs from the perturbative one by le…

A modification of minimal analytic QCD at low energies
G. Cvetic, C. Valenzuela, I. Schmidt
We present an approach which allows for modifications of the (minimal) analytic QCD model of Shirkov, Solovtsov et al. The discontinuity function of the (minimal) analytic QCD coup…

Spontaneous CP Symmetry Breaking in Top-condensation Models
Cristian Valenzuela
In this thesis we study top-condensation models of electroweak symmetry breaking. In particular we investigate a scenario in which the CP symmetry is broken spontaneously due to th…
