How relevant is the electric charge of quarks within hadrons?
Given that each quark flavor has a particular electric charge (i.e., either +2/3 or -1/3): how do these charges effect the internal dynamics of hadrons? Do the attractive and repulsive effects of ...

Collision of two positrons: Is there any "strong force" that binds two positrons together to produce a positron-positron pair with $+2e$?
I want to know if it is possible to hardly collide two positrons with each other to produce a pair with $+2e$. Indeed, I want to know if there is a strong force, similar to those binding protons ...

Why is the electromagnetic force not an emergent property of the strong force? [closed]
Two up quarks in a proton lead to an imbalance, which results in the proton having the ability to attract electrons. Two down quarks in a neutron lead to balance in the electromagnetic force, leading ...

EM force or Strong force?
$$
e^- + p \rightarrow \Delta^{++} + e^- + \pi^-
$$
Apparently this reaction is mediated by the EM force. My question is: how do you know it isn't the strong force?
Yes, all the particles have ...

Strength of strong force and electromagnetic force
In this link, it is claimed that the strength of the strong force w.r.t. the E&M force is about 137 times larger. Does this have anything to do with the fine structure constant?

Does Temperature Affect electromagnetic/Strong/Weak Force?
From what I understand, the energy or temperature of a structure with mass has no effect on the gravitational force it emits. Is the same true for the other fundamental forces?
What would happen to ...

Why is diproton unstable? [duplicate]
Diproton is an isotope of helium without any neutrons. It commonly forms in the Sun, where protons are fused constantly. However, it is extremely unstable, and will revert back to two protons almost ...
