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. ...

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 do the strong and weak forces relate to nuclear fission and fusion?
Fission and fusion are due to the strong and weak forces, but it is unclear to me which is responsible for which.

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 ...

How are length and time scales for the different kinds of interactions (strong, weak, electroweak) determined?
I was recently asked what the length scale of the strong interaction is and found my self a bit lost at the question. A quick Google search revealed a result of $10^{-15}\,\text{m}\approx 1\,\text{GeV}...

Why does the weak nuclear interaction have a shorter range than strong nuclear interaction?
My textbook says:
"Weak nuclear interaction acts on protons, neutrons, electrons and neutrinos in order to bring about beta decay. It has very short range (10-18m)"
"Strong nuclear interaction ...

Half-life of $W$ and $Z$ bosons
$W$ and $Z$ bosons should decay through weak interaction. But their half-life is around $\tau = 10^{-25} s$ which is a typical value for particles decaying through strong force (instead of a $10^{-12}-...

How can K (kaon) and Σ (sigma particle) be created quickly via the strong interaction and decay slowly via the weak interaction?
So the kaon particle (K) and the sigma particle (Σ) are created very quickly through the strong interaction and decay slowly through the weak interaction.
How is this so? Is this not some kind of ...

How can I determine the interaction knowing the decay formula?
I know the kind of interaction occurring in very common reaction. For example, I know that the interaction:
$e^- + e^+ \longrightarrow \mu^+ + \mu^-$
is driven by the electromagnetic force (there is ...

Strangeness of elementary particles
What is the property, whose violation led to the assumption of strangeness? Prior to the discovery of strangeness was it assumed that particles that are produced by strong interactions can decay only ...

Difference between weak and strong interactions?
This was a statement given in my class:
"Strangeness is conserved in the strong and electromagnetic interactions, but not in a weak interaction "
But could someone please tell me how we ...

Why strong and weak forces are short range? [closed]
Why are the strong and weak nuclear forces short range?
Are quarks confined or welded together?
Why are elementary particles confined at short range?
Or is color confinement color welding?
