17. (a) As far as the conservation laws are concerned, we may cancel a proton from each side of the reaction equation and write the reaction as px→+Λ0.Since the proton and the lambda each have a spin angular momentum of =2, the spin angular momentum of xmust be either zero or =. Since the proton has charge +eand the lambda is neutral, xmust have charge +e. Since the proton and the lambda each have a baryon number of +1, the baryon number of xis zero. Since the strangeness of the proton is zero and the strangeness of the lambda is –1, the strangeness of
