21. (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 + Λ 0 . Since the proton and the lambda each have a spin angular momentum of = 2 , the spin angular momentum of x must be either zero or = . Since the proton has charge + e and the lambda is neutral, x must have charge + e . Since the proton and the lambda each have a baryon number of +1, the baryon number of x is zero. Since the strangeness of the proton is zero and the strangeness of the lambda is –1, the strangeness of
