What's the difference between "repulsion force carrier and
attraction force Carrier" in electromagnetism interactions?
We know that these two messenger photons should be
distinguished. But in what features and details?

I've never heard of these terms. :confused:

So far as I know there's no distinction.

Can you provide a quote and a link to where you saw this? :smile:​
 
my apologize,i have ever seen that anywhere to provide a quote. but i meant how two specific charges know when interact by attraction force or repulsion force?
 
(One charge doesn't "know" that the other charge is there, it only "knows" that it is in an electric field, but anyway …)

The field works the same way whether the charge is positive or negative.

"Messenger" photons (and electrons), usually called "virtual" photons (and electrons), are only a mathematical idea that helps to describe the approximations in perturbation theory in quantum field theory.

They don't literally "carry" the force. :smile:
 

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}...
