Messenger photon in electromagnetism intractions

[mohsen1989]

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.

So far as I know there's no distinction.

Can you provide a quote and a link to where you saw this? ​

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.
