How is strong coupling constant related to cross section?
I've been looking through different Pdfs /articles on strong coupling constant and nearly all of them involve cross section, I've understood what cross section is but not how is it connected to ...

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 ...

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 ...

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 ...

Do hadrons only interact via strong interaction?
According to my revision guide baryon and mesons always interact via the strong interaction.
Does this hold for baryon-baryon interactions? meson-meson?

Is there an equation for the strong nuclear force?
The equation describing the force due to gravity is $$F = G \frac{m_1 m_2}{r^2}.$$ Similarly the force due to the electrostatic force is $$F = k \frac{q_1 q_2}{r^2}.$$
Is there a similar equation ...
