How does dynamical mass generation works ?

AI Thread Summary
Dynamical mass generation in quantum field theory (QFT) describes how effective quark mass arises from interactions with virtual particles, particularly influenced by the strong force. The effective quark mass varies with momentum, reflecting the quark's interaction with its environment. At low energies, the strong coupling constant increases due to asymptotic freedom, allowing many virtual particles to become real, thus generating mass. Clarification on the definition of effective quark mass is sought, emphasizing its significance in understanding these interactions. The discussion highlights the complexities and nuances of mass generation in QFT.

How does dynamical mass generation works ?

In QFT-textbooks, the process of dynamical mass-generation is often used.
For example one gets an effective quarkmass as a solution of the Schwinger
Dysonequation. This mass is dependent on the quarks momentum.The effective quarkmass as a function of the momentum gives an image of the
interaction between a quark and its surrounding virtual particles. For
low-energy quarks, the strong force coupling constant is very large because
of asymptotic freedom. So in this condition, many virtual particles become
real because of the strong interaction and thus quarkmass is generated.Is this conclusion right or am I making e few mistakes here?Can anyone give me a clear definition of the effective quarkmass, what does
is really mean?

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
