Dynamical symmetry breaking in 4-fermion models in 2+ 1 dimensions is quantitatively
studied. We use the 1/N expansion and show that these models are renormalizable in this …

We present a synopsis of Higgs-boson phenomenology at one loop in the standard model.
Two-loop effects are reported on as far as present knowledge goes. The phenomena are …

Chiral perturbation theory provides a systematic large volume expansion in powers of 1/L d−
2, where L= V 1/d is the size of the system and d> 2 is the dimension. Different observables …

We review recent efforts to explore the information on masses of heavy matter particles,
notably of the top quark and the Higgs boson, as encoded at the quantum level in the …

Abstract Brout–Englert–Higgs physics is one of the most central and successful parts of the
standard model. It is also part of a multitude of beyond-the-standard-model scenarios. The …

Ever since it was first proposed the neutrino has played a crucial role in the advancement of
our understanding of particle physics. The neutrino was first conjectured by W. Pauli in a …

In this lecture we discuss the basic ingredients for gauge invariant quantum field theories.
We give an introduction to the elements of quantum field theory, to the construction of the …

In this paper we consider the phenomenology of a nonstandard Higgs boson in longitudinal
gauge boson scattering. First, we present a composite Higgs model [based on an SU (4)/Sp …

Because of two 3 σ anomalies, the standard model (SM) fit of the precision electroweak data
has a poor confidence level, CL= 0.010. Since both anomalies involve challenging …

Using a combination of analytic mean field techniques and hybrid Monte Carlo simulations,
we determine the phase structure of a 4d Yukawa theory with a one-component scalar field …
