Q

is strangeness conserved in strange particle decay

A

no

17
Q

for a strange interaction to be viable the strangeness can only

A

increase by 1
decrease by 1
remain the same

18
Q

how to work out an unknown particle from a particle interaction

A

state the force responsible for the interaction

write out the values for the conservation laws

use the values to work out the conservation laws for the unknown particle

19
Q

why are decay equations limited

A

as they dont show the exchange particles
