Yukawa exchange model
For my physics class I have to answer the following question.
Why do we need two pion exchange and rho meson exchange , and not just one pion in order to explain the strong interaction.
My thought is ...

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 ...

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?
Thanks

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 can the Euler beta function be interpreted as a scattering amplitude?
The Wikipedia article on the Veneziano Amplitude claims that the Euler beta function can be interpretted as a scattering amplitude. Why is this?
In another word, when the Euler beta function is ...

Does strong interaction care about mass? (+ Isospin question)
So in the journey of trying to understand more about the strong interaction I have encountered some passages linking mass with strong interaction. Like from Greiner and Müller Quantum Mechanics - ...

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 ...
