Questions tagged [strong-force]
The strong force or interaction is responsible for the confinement of quarks inside hadrons and the binding of nucleons inside a nucleon, and it is described by the gauge theory of QCD. It provides most of the mass of ordinary matter, which is dominated by the nucleons, proton and neutron: over 99% of the mass of these is attributable to the strong-force field energy. Use where technical details of QCD are not warranted.

Fermi momentum vs. nucleon-nucleon momentum
Are there differences between the terms 'Fermi momentum' and 'nucleon-nucleon momentum' and if so, what are they?
I have stumbled across inconsistent terminology in the literature. Some books call the ...

Momentum distribution of nucleons inside the deuteron (Paris potential)
I am looking for a graph that shows the momentum distribution of nucleons inside the deuteron.
Side note: I know that several models for nucleon-nucleon potentials exist, such as the Paris, Bonn or ...

How does pion exchange cause protons and neutrons to be attracted to each other? [duplicate]
I read that neutron and protons are attracted through exchanging pions between each other. However, as far as I understand, they are just exchanging a meson, not any force carriers. What causes them ...

How are $\pi$ Mesons Created in the Residual Strong Interaction?
Watching this episode of PBS Space Time, they run an animation of how pi mesons are exchanged by nucleons as the residual strong interaction to overcome proton electromagnetic repulsion.

Is there an experimental set up that would produce a "macroscopic" a weak or strong nuclear force fields?
I was wondering if there is an experimental set up that would produce something equivalent to a classical electromagnetic field for the weak and strong nuclear forces. I know that the those forces are ...

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 ...

What is the mean internucleon distance in a nucleus?
I am finding some conflicting information which is resulting in some confusion when teaching the topic of nuclear physics to high school students.
The residual strong nuclear force has an attractive ...

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?

Separation energy of nucleons and Coulomb barrier
My question is related to this topic: Tunneling of alpha particles. Unfortunately it didn't quite solve my doubts.
My professor and the book I'm reading (Particles and Nuclei: An Introduction to the ...

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 ...

Coulombian barrier fission
Protons and neutrons in a nucleus are both in a well of $\sim$ 50 MeV (obviously that depends on the specific nucleus), but the shape of the quantum well is different because there is the Coulomb ...

What is the significance of the Strong interaction between a pair of Neutrons?
When we are introduced to the Strong Nuclear force, we are told that it prevents the nucleus from flying apart because of the electric repulsion between protons. But there is no such repulsion between ...

Question about semiclassical approach to QCD
I'm struggling to understand the usefulness of the semiclassical approach to QCD. In particular, by using this approach, we can analyze the vacuum structure of QCD, including theta-vacua, $n$-vacua, ...

The difference between neutron and proton separation energy of a nucleus
For a given nucleus, why does the value of the neutron separation energy $S_n$ differ from the value of the proton separation energy $S_p$? One of the reasons that is immediately obvious is that the ...
