Non-perturbative approach to high-energy physics
I know that main numerical approach to modeling high-energy physics events are Monte-Carlo event generators. But they are using perturbative description of collision and decay processes of particles.

Why is the chiral condensate a negative quantity?
The chiral condensate serves as an order parameter for the chiral phase transition. Thus, it is a finite quantity in one phase and vanishes in the other phase. It is given as a vacuum expectation ...

Non-Perturbative effects QCD and the Standard Model?
I read in an article that the Standard Model leaves unanswered questions about the non-perturbative effects of the QCD.
I have basic knowledge about the perturbative and non-perturbative QCD. Could ...

complicated QCD Color factor formula?
I was doing higher order calculations for purely gluonic system and came across complicated color factors like the product of six structure constants product $f_{a_1a_2a_3}f_{a_4a_2a_7}f_{a_7a_8a_1}f_{...

Decay of some particle involved quarks vs mesons as outgoing states
Let's have decay width of some mother particle into the state which involves hadrons. For simplicity, let's assume that creation of hadrons (on diagram) is possible only through electroweak vertices (...
