What is Particle Physics?

Particle physics is a branch of physics that deals with the study of particles that make up all atoms and their reactions. Particle physics is an abstract and advance level of physics. Strong fundamentals of physics and mathematical skills are required to study Particle physics or do research in the Particle physics field. However, Particle physics is very fascinating and a very exciting field of theoretical physics.

How many particles have been discovered in Particle Physics?

There are more than 300 subatomic particles Particle physicists have identified. There are more particles being discovered and identified in Particle physics observations all the time. These particles in Particle physics are categorized into many classes of particles according to thier:

  • mass
  • electric charge
  • spin
  • magnetic moment, and
  • interaction
What are subatomic particles and what do subatomic particles include?

Subatomic particles in Particle physics include:

  • Elementary particles. Elementary particles are indivisible so they are considered fundamental particles or units of matter. Elementary particles are: 
    • Quarks,
    • Leptons, and
    • Gauge Bosons
  • Hedrons. Hedrons are composite particles in Particle Physics. What are composite particles? Composite particles or hedrons are made up of two or three quarks. Hedrons are:
    • Baryons (examples of Baryons are proton and neutron), and
    • Mesons
What are stable particles in Particle physics?

The only stable particle in Particle physics are:

  • Quarks,
  • Protons,
  • Electrons,
  • Neutrinos
