Photons are classified as bosons because they have integer spin (s = 1) and follow Bose-Einstein statistics. Characteristics include:
• Force carriers: Photons mediate electromagnetic interactions.
• No Pauli exclusion: Unlike fermions, multiple photons can occupy the same quantum state.
• Examples: Other bosons include gluons, W/Z bosons, and the Higgs boson.
