How exactly does the strong interaction decrease with distance?
So, we all know that the strong force asymptotes but the thing is I've never gotten a good description as to why
Can someone explain;
How the Strong force weakens with distance? I think I have got ...

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 ...

Kinetic energy of quarks in a proton
If we say that a proton has a kinetic energy of 50 GeV, can we say that each of the three quarks that compose it have roughly a mean energy of $\approx \frac{50}3=17$ GeV?

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 ...

Why are there no particles that ONLY interact via the strong force?
The title speaks for itself really: I noted everywhere I learned about fundamental interactions that there are particles that interact ONLY via the Weak Force (and gravity, if it counts)(e.g. ...

A very basic question about particle (leptons, hadrons) interactions
Suppose a particle reaction $A+B\to C+D$ is allowed in nature. Then, the reactions,
\begin{align}
A&\to \bar{B}+C+D,\\ \bar{C}+\bar{D}&\to \bar{A}+\bar{B},\\ B&\to\bar{A}+C+D,\\& \...

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 ...

What causes the difference in ranges of forces?
What causes the difference in ranges of forces? In other words, why is it that the weak force acts only at small distances whereas the Coulomb force has a very large range?

How scientists know which particle is/is not influenced by strong force?
Muon is said to be uninfluenced by strong force, unlike pion.
My question is, based on which experiment, scientists determine a particle is influenced by strong force or not?
Edited:
Thank you for the ...

Are gluon particles analogous to flux tubes?
I've always been told gluons are the force "particles" mediating the strong force. And I've learned that Fluxtubes are what hold quarks together. Are these fluxtubes the "particle" ...

How do mesons explain nuclear stability?
I understand that nuclear stability is explained by the presence of the residual nuclear force, which in turn is a result of the strong nuclear force, which I believe, is mediated between quarks via ...

On $\Delta^{+}$ particle decay
Using isospin notation
$$
\Delta^+=\left|\frac 3 2,\frac 1 2\right\rangle=\frac{1}{\!\sqrt{3}}\bigg(|duu\rangle+|udu\rangle+|uud\rangle\!\bigg)
$$
It is known all of the $\Delta$ baryons with mass ...

Does the energy of the strong force have mass? [closed]
The mass of a proton is said to predominantly be "comprised" of the mass of the strong force interactions within the proton. Logically, one could conclude that the energy (the strong force ...

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?
