On $\Delta^{+}$ particle decay
Using isospin notation
$$
\Delta^+=\left|\frac 3 2,\frac 1 2\right\rangle=\frac{1}{\!\sqrt{3}}\bigg(|duu\rangle+|udu\rangle+|uud\rangle\!\bigg)
$$
It is known all of the $\Delta$ baryons with mass ...

If isospin is conserved in a given strong interaction, can we say that the interaction is certainly allowed?
If isospin is conserved in a given strong interaction, can we say that it is certainly allowed and it's not needed to check other conservation rules like baryon number, electric charge etc. ?

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 ...

Experimental proof for isospin conservation of strong interaction
I am having a surprisingly hard time to find direct experimental results for the (approx.) conservation of isospin in strong interactions. The canonical examples seem to be $\omega \! \to 3\pi^0$ and $...

Isospin conservation for total isospin or third component of isospin?
In a strong interaction, is the total isospin or just its third component conserved? Or are they both conserved?

Why is the strong interaction blind to the third component of Isospin?
Neutron and the proton have different values of $I_3$, the third component of the Isospin. Yet the strong interaction cannot distinguish between them. Why is this so? I can't understand this.
The ...

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 - ...
