2. Standard Model of Particle Physics:
- Overview of the standard model and its components
- Fundamental forces and particles in the standard model (electromagnetic, weak, strong, and gravitational forces)
- Interaction between particles through exchange of force-carrying particles (gauge bosons)

3. Elementary Particles:
- Properties and characteristics of elementary particles (quarks, leptons, and gauge bosons)
- Quark flavors and color charge
- Lepton families and their properties
- Higgs boson and its role in particle mass generation

4. Particle Interactions:

5. Fundamental Forces:
- Electromagnetic force and its properties (Coulomb's law, electric and magnetic fields)
- Weak force and its role in particle decay processes
- Strong force and its characteristics (color charge, confinement, and asymptotic freedom)
- Gravitational force and its relationship to mass and distance

6. Experimental Techniques in Particle Physics:
- Particle accelerators and detectors used in experiments
- Principles of operation of accelerators (linear accelerators, cyclotrons, synchrotrons)
- Types of particle detectors (ionization chambers, scintillation detectors, calorimeters)

7. Applications of Particle Physics:
