Answer to Problem 31P

The strangeness is not conserved.

Explanation of Solution

The reaction is,

Λ0p+π+

A strangeness of Λ0 is -1, the strangeness of p is 0 and the strangeness of π+ is 0.

Therefore,

10+010

The difference in strangeness in the reaction is,

Δs=10=10

  • Δs is the variation in strangeness in each side of the reaction

Thus, the strangeness is not conserved.

Conclusion:

The strangeness is not conserved.

Answer to Problem 31P

The strangeness is conserved.

Explanation of Solution

The reaction is,

π++pΛ0+K+

A strangeness of Λ0 is -1, the strangeness of p is 0 , the strangeness of K0 is +1 and the strangeness of π+ is 0.

Therefore,

0+01+100

The difference in strangeness in the reaction is,

Δs=00=0

  • Δs is the variation in strangeness in each side of the reaction

Thus, the strangeness is conserved.

Conclusion:

The strangeness is conserved.

The reaction is,

p¯+pΛ0¯+Λ0

A strangeness of Λ0 is -1, the strangeness of p is 0 , the strangeness of Λ0¯ is +1 and the strangeness of p¯ is 0.

Therefore,

0+01+100

The difference in strangeness in the reaction is,

Δs=00=0

  • Δs is the variation in strangeness in each side of the reaction

Thus, the strangeness is conserved.

Conclusion:

The strangeness is conserved.

Therefore,

0+00101

The difference in strangeness in the reaction is,

Δs=10=1

  • Δs is the variation in strangeness in each side of the reaction

Thus, the strangeness is not conserved.

Conclusion:

The strangeness is not conserved.

Answer to Problem 31P

The strangeness is not conserved.

Explanation of Solution

The reaction is,

ΞΛ0+π

A strangeness of Λ0 is -1, the strangeness of Ξ is -2 and the strangeness of π is 0.

Therefore,

21+021

The difference in strangeness in the reaction is,

Δs=21=10

  • Δs is the variation in strangeness in each side of the reaction

Thus, the strangeness is not conserved.

Conclusion:

The strangeness is not conserved.
