⚛️ GLUEBALLS: MATTER OF FORCE
🔬 Why in News?
New BESIII data strengthens evidence for glueballs—hypothetical particles made entirely of gluons, the carriers of the strong force.
🧠 THE CONCEPT
🔹 Quarks → Build protons & neutrons
🔹 Gluons → Carry the strong interaction
🔹 QCD → Theory explaining strong interactions
🔹 Glueballs → Bound states made only of gluons
🔹 X(2370) → Key glueball candidate
🔹 BESIII → Particle-physics experiment in Beijing
📚 PRELIMS BOOSTER
⚛️ 4 Fundamental Forces
Gravity • Electromagnetic • Strong • Weak
💥 Strong Force → Holds quarks together inside protons/neutrons and contributes to nuclear binding.
💡 Key Analogy:
Photon → Electromagnetic force
Gluon → Strong force
