Question

Supply the simplest missing particle in the following reactions.

*p*+ *p*→ *p*+Λ0 +?

*p*+*p*→*n*+?

π − + *p* → Ξ0 + *K* 0 + ?

*K* − + *n* → Λ0 + ?

ντ +*p*→*n*+?

Answer #1

a)

This reaction should also contain a positively charged kaon. The simplest reason for this is that the total charge before and after the reaction should remain conserved.

b) . This is a type of associated strangeness production where two emitted particles will have the opposite strangeness in order to conserve the strangeness before and after reaction.

c) . There will be no more product other than these because all quantities are conserved here.

d) . The production of pion will ensure the charge conservation in this reaction.
