can anyone explain me about the differences between color and strong force?Though there are four fundamental forces so from where does the color force come?
 
Physics news on Phys.org
If I am not mistaken, quarks are held together by gluons and like quarks have up, down, charm, strange, top and bottom with their anti quark partners, gluons are called red, green and ( forgot one more color) and my the exchange of gluons, the quark remain together. In fact, the carriers of strong force are gluons and they carry color charge.
In short, just like the photons are the carriers of EM force, gluons are the gauge bosons of strong force and they keep the quarks intact.
Its better if you look at wikipedia and do some research on QCD.

"Color force" is another name for the strong force.

But after posting this question I searched more articles and found the following extract saying

"Since quarks make up the baryons, and the strong interaction takes place between baryons, you could say that the color force is the source of the strong interaction, or that the strong interaction is like a residual color force which extends beyond the proton or neutron to bind them together in a nucleus."
 
The color force is the fundamental force. It holds quarks together inside of nucleons. Even though nucleons are "color neutral", there is a small amount of interaction between nuclei thanks to the color force "bleeding over" to a nearby nucleon that gives rise to the very short range strong force. This is similar to how neutral atoms can be still be attracted to each other at close range.

Perhaps a better term would be to call the interaction between nuclei the "nuclear force" and just use the strong force and color force interchangeably.

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...
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}...
