PID Weak Interaction Theory

This post presents a brief introduction to the field theory of weak interactions, developed recently by the authors, based only on a few fundamental principles: the action is the classical Yang-Mills action dictated uniquely by the gauge invariance and the … Continue reading

Problems in Classical Electroweak Theory

The classical electroweak theory forms the core of the standard model of particle physics. The great success of both the electroweak theory and the standard model include e.g. the prediction of the intermediate vector bosons and the Higgs boson. In … Continue reading

On Unification of Four Fundamental Interactions

I. There are four fundamental interactions in Nature–the electromagnetism, the gravity, the strong and the weak interactions. The current route of the unification of the four interactions is under the following assumption: there is only one interaction of Nature, which, … Continue reading

Gauge Field Theory For Strong Interactions

This post presents a brief introduction to the gauge field theory of strong interactions, developed recently by the authors, based only on the gauge invariance, the principle of Lorentz invariance, the principle of representation invariance (PRI) and the principle of … Continue reading

Unified Field Theory

This post presents a brief introduction to the unified field theory of four fundamental interactions, developed recently by the authors [3, 4], based only on a few fundamental principles and symmetries. The main breakthrough is the introduction of two basic … Continue reading

Yang-Mills Theory and Principle of Representation Invariance (PRI)

The objectives of this post are 1) to briefly introduce the basic formulation of the gauge theory, and 2) to postulate the principle of representation invariance (PRI): Principle of Representation Invariance (PRI) [Ma-Wang, 2012] An gauge theory must be invariant … Continue reading
