The document provides an overview of the Standard Model of elementary particles. It classifies particles into fermions like quarks and leptons, and bosons which act as force carriers. Quarks are grouped into three families and combine to form hadrons such as baryons, made of three quarks, and mesons consisting of a quark and antiquark. Bosons include photons, gluons, W/Z bosons, and the hypothetical graviton. Specific bosons mediate particular forces - photons with electromagnetism, gluons with the strong force, and W/Z bosons with the weak force.

22. PHOTONS
Photons are E/M force carriers.
 Electricity
 Magnet,etc

23. W/Z BOSONS
• W/Z Bosons are weak nuclear force carriers.
B-decay
Anti-Neutrino,etc

24. GLUONS
• Gluons are strong nuclear force carriers.
Due to this protons and neutrons are exist together in the nucleus.

25. GRAVITONS
• Gravitons are Gravitational force carriers.ssss
We have still not found the particles which identify the
gravitational force
