The Weak Nuclear Force

Question 1

Why was the neutrino found in beta decay

Answer 1

In beta decay a neutron turns into a proton and releases a beta particle

The problem with beta decay was that the electron had a range of energies

This meant another massless particle with variable speeds was being made, the neutrino

Question 2

What is the weak interaction the only interaction to do

Answer 2

Change quarks into other types of quarks

This means in some reactions up and down quarks turn into strange quarks

This means strangeness is not conserved
