Particle Physics

Question 1

Conservation in a Nuclear Reaction:

Answer 1

Mass-energy is conserved
Momentum is conserved
Electric charge is conserved

Question 2

Pair Production

Answer 2

Pair production is the creating of two particles from energy.
In the process a particle and its anti-particle are produced.
Momentum and electric charge are conserved.

Question 3

Elementary Particle

Answer 3

An elementary particle is a particle that has no other particles inside it or has no subparts to it

Question 4

Leptons

Answer 4

A lepton is a particle that does not feel the strong force

Question 5

Hadron

Answer 5

A particle that feels the strong force is called a hadron

Question 6

Quarks

Answer 6

Quarks are elementary particles out of which baryons and mesons are made. They have a charge of plus/minus 1/3 e or plus/minus 2/3 e

Question 7

Mesons

Answer 7

A meson is made up of any one quark and any one antiquark

Question 8

Baryons and Antibaryons

Answer 8

A baryon is made up of any three quarks.

An antibaryon is made up of any three antiquarks
