1Gauge theory — For a generally accessible and less technical introduction to the topic, see Introduction to gauge theory. In physics, a gauge theory is a type of field theory in which the Lagrangian is invariant under a continuous group of local transformations …
2BRST quantization — In theoretical physics, BRST quantization (where the BRST refers to Becchi, Rouet, Stora and Tyutin) is a relatively rigorous mathematical approach to quantizing a field theory with a gauge symmetry. Quantization rules in earlier QFT frameworks… …

4QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… …
5MHV Amplitudes — In theoretical particle physics, maximally helicity violating amplitudes are amplitudes with n external gauge bosons, where n 2 gauge bosons have a particular helicity and the other two have the opposite helicity. These amplitudes are called MHV… …
6Status of special relativity — Special relativity (SR) is usually concerned with the behaviour of objects and observers (inertial reference systems) which remain at rest or are moving at a constant velocity. In this case, the observer is said to be in an inertial frame of… …
7Floer homology — is a mathematical tool used in the study of symplectic geometry and low dimensional topology. First introduced by Andreas Floer in his proof of the Arnold conjecture in symplectic geometry, Floer homology is a novel homology theory arising as an… …

9BPST instanton — The BPST instanton is the instanton with winding number 1 found by Belavin, Polyakov, Schwartz and Tyupkin. It is a classical solution to the equations of motion in Euclidean space time (i.e. after Wick rotation), meaning it describes a… …
