What kind of limitations are there for trying to split up the quarks from their binding formation?
 
Physics news on Phys.org
The force between them goes to infinity as a function of separation distance.
 
Isn't this problem of infinite force between quarks like the infinite of every force which decreases 1/r^a with distance r, and a>0, as r->0.

I'm not convinced this is the only restriction for finding quarks in groups rather than individuals.
 
That is the reason for why you, classically, can not force two chargers of equal type arbitrary close.

Another feature is the criterion of colour-neutrality, all physically observable states must have 0 colour charge.

I should say I disagree :smile:

The strong coupling constant at large distances
 
I was referring to the quark-quark potential in e.g. quarkonia. That potential becomes constant at the "string breaking" scale.
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
