Chapter 44: Q15P (page 1364)

Which conservation law is violated in each of these proposed reactions and decays? (Assume that the products have zero orbital angular momentum.)
$(a) {鈭�}^{0} 鈫� {pK}^{-}; (b) 惟^{-} 鈫� {鈭�}_{}^{-} + 蟺^{0} (S = - 3, q = - 1, m = 162 MeV / c^{2}, and m_{s} = \frac{3}{2} 蹿辞谤惟); (c) K^{-} + p 鈫� 鈭� 0 + 蟺^{+}$

Short Answer

(a) Energy

(b) Strangeness.

Step by step solution

Conservation law

A principle that states that a certain physical property does not charge in the course of time within an isolated physical system. or

The law states that the total energy of an isolated system does not change.

Solve.(a)∧0→p+K-

1) Solution.

${鈭�}^{0} 鈫� p + K C h a n g e 0 + 1 - 1 S p i n \frac{蟺}{2} \frac{蟺}{2} \frac{蟺}{2} B a r y o n n u m b e r + 1 + 1 - 1 S t r a n g e n e s s - 1 0 - 1 R e s t e n e r g y 1115.6 938.3 493.7$

Hence, Energy cannot be conserved

Solve.(b)Ω-→∑-+π0s=-3,q=-1,m=1672MeV/c2,ms=32forΩ

1) Solution.

$惟^{-} 鈫� {鈭�}_{}^{-} + 蟺^{0} Charge - 1 - 1 0 Baryon number + 10 + 10 0 Spin \frac{蟺}{2} \frac{蟺}{2} 0 Strangeness - 3 - 1 0 Rest energy 1680 1197.3 13.5$

Hence, Charge can not be conserved.

Solve(c)K-+p→∧0+π+

1) Solution.

$K^{-} + p 鈫� {鈭�}^{0} + 蟺^{+} Rest energy 493.7 938.3 1115.6 139.6 Strangeness - 1 0 - 1 0 Spin 0 \frac{蟺}{2} \frac{蟺}{2} 0 Baryon number 0 + 1 + 1 0 Charge - 1 + 1 0 + 1$

Hence, Charge can not be conserved.
