This is more of a question to see if I'm doing it right more than anything. The first Feynman...
Doing a bit of revision at the moment and I've been looking at the baryon spin-1/2 octet and the spin 3/2 decuplet. I've noticed that a lot of particles have the same quark composition. For instance the Δ0 particle from the 3/2 ducuplet has the same quark composition as a proton. Now I know that...

f'(p) is the Fourier transform of f(x). Show that the Fourier transform of e^(ip0x)f(x) is f'(p - p0). (using f'(p) for transform)
Homework Equations
f(x) = 1/√(2pi) ∫e^(ipx) f'(p) dp (intergral from -∞ to ∞)
f'(p) = 1/√(2pi) ∫e^(-ipx) f(x) dx (also from -∞ to ∞)

Homework Statement
Rewrite the state |ψ⟩ = √(1/2)(|0> + |1>) in the new basis.
|3⟩ = √(1/3)|0⟩ + √(2/3)|1⟩
|4⟩ = √(2/3)|0⟩ − √(1/3)|1⟩
You may assume that |0⟩ and |1⟩ are orthonormal.

Forgot to say, I now see that kaon pair production must be a product of the strong force. Just trying to understand how and when I need to worry about the isospin. Or can there be two types of interaction happening simultaneously?
Thanks for your reply mfb,
Think this is where i was getting confused.
If the collision is: P + P → K+ + K- + P + P
Then the conservation laws for the isospin aren't conserved?
Following the order of the collision above the isospin would be: 1/2 + 1/2 → 1/2 + 1/2 + 1/2 + 1/2, 1 ≠ 2...
