1
Q
what is conserved in all interactions
A
Charge (energy)
Baryon no
lepton no. (specific to the leptons)
mass
energy
momentum
2
Q
what is specifically only conserved in strong interactions
A
strangeness
(hadrons interacting / hardon decaying)
3
Q
explain the productions of π-mesons in the annihilation process of a proton and antiproton
A
where only 1 corresponding quark and antiquark anhiliate another, leaving 4 quarks, that go off in pairs producing mesons
(usually, they are not corresponding quarks and antiquarks or they would of anhiliate another)
