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 ...

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 ...

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 ...

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 ...

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?

Cause of Strong force
What is the origin and cause of the strong interaction which occurs between the nucleons? I have read that it is caused by the exchange of mesons but what then ultimately causes this meson exchange to ...

Like quark baryons
Why aren't there particles like neutrons or protons but with 3 up or 3 down quarks, instead of 2 up/1 down or 2 down/1 up. Does there have to be 2 different types of quarks for the strong force to ...

Is isospin magnitude $I$ conserved? [duplicate]
Here is a table of isospin conservation in certain reactions.
It is often loosely stated that 'isospin is always conserved in strong interactions', but it is never clear whether they mean total ...

How can I build up my knowledge in particle physics to the level that I can calculate the path of elementary particles in a perfect vacuum?
I have to write a research paper (don't know the exact english translation) for school. The question I want the paper to answer/discuss is: 'Can the universe be predicted at sub-atomic level?'
The ...

How is strong coupling constant measured through deep inellastic scattering (DIS)?
is deep inelastic scattering a process? and how is it (DIS) used to measure strong coupling constant?
the traditional method of measuring $α_S$ in deep inelastic scattering is from the strength of ...
