Conservation Rules

Question 1

What are conservation rules?

Answer 1

rules that particles must obey when they react

Question 2

What rules apply to all changes in science?

Answer 2

conservation of energy and charge

includes rest energy of particles

Question 3

What rules are only used for particle and antiparticle interactions and decays?

Answer 3

conservation of the number of leptons

conservation of strangeness

Question 4

Are baryons and mesons conserved?

Answer 4

if we assign the baryon number:

+1 for any baryon and

-1 to any antibaryon 0 to any meson or lepton

baryon number is conserved

Question 5

What can only occur in weak interaction?

Answer 5

changing of strangeness

Question 6

Why do no further reaction occur after the decay of a neutron? What are the products that arise?

Answer 6

_{_}

n → p⁺ + V_e + β^-

the only products remaining are electrons and antineutrinos which are stable

and a proton which is the only stable baryon
