Review of Particle Physics

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

Renormalization and blow up for the critical Yang-Mills problem

Joachim Krieger, Daniel Tataru

We consider the Yangs-Mills equations in 4 + 1 dimensions. This is the energy critical case and we show that it admits a family of solutions which blow up in finite time. They are obtained by the spherically symmetric ansatz in the SO(4) gauge group and re ...

Anomalous solitons

Matthias Schmid

Solitons are stable, non-singular solutions to the classical equations of motion of non-linear field theory. Their energy is localized and finite and their shape remains unaltered during propagation. For this reason they represent particle-like states in f ...

Review of Particle Physics

Olivier Schneider, Pierre Vogel, Greig Alan Cowan, Jian Liu

This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2778 new measurements from 645 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...

Non-perturbative processes with Fermion number non-conservation in different models of particle physics

Yannis Burnier

When a classical conservation law is broken by quantum corrections, the associated symmetry is said to be anomalous. This type of symmetry breaking can lead to interesting physics. For instance in strong interactions, the anomaly in the chiral current is i ...

Gauge-Higgs unification in orbifold models

Claudio Scrucca, Andrea Wulzer

Six-dimensional orbifold models where the Higgs field is identified with some internal component of a gauge field are considered. We classify all possible T-2/Z(N) orbifold constructions based on a SU(3) electroweak gauge symmetry. Depending on the orbifol ...

The Eulerian-Lagrangian transformation in two-dimensional random flows

Jan Sickmann Hesthaven, Allan Svejstrup Nielsen

The relation between the Eulerian and the Lagrangian correlation functions is studied in two spatial dimensions. Simple analytical expressions for the full space-time varying Eulerian correlation are derived solely on the basis of the one-dimensional waven ...

Baryon asymmetry of the universe in the standard electroweak theory

We study the interactions of quarks and antiquarks with the changing Higgs field during the electroweak phase transition, including quantum mechanical and some thermal effects, with the only source of CP violation being the known CKM phase. We show that th ...

Radiative Quark Masses Constrained by the Gauge Group Only

Riccardo Rattazzi

We discuss the possibility of obtaining the observed pattern of quark masses and mixings as a consequence of radiative corrections, gauge invariance and particle content of the theory. We do not allow any kind of additional symmetry, such as family and dis ...
