Which interaction is responsible for each of the following d

Which interaction is responsible for each of the following decays: A gravitational interaction B weak nuclear interaction C strong nuclear interaction D electromagnetic interaction

Solution

A ) Weak Nuclear Interaction

B ) Weak nuclear interaction

C ) Electro magnetic interaction

D ) Weak nuclear interaction

Protons, neutron an pions have no strangeness. In decay processes involving the strong interaction strangeness is conserved. In decay processes involving the weak interaction, such as K-decay or hyperon decay, strangeness is not conserved. This was the first case that some quantum numbers were conserved in strong interactions and electromagnetic interactions, but not in weak interactions.
