: LHC PHYSICS: CERN’s Large Hadron Collider is a 27 km particle accelerator. Protons are accelerated to energies of up to 6.8 TeV per beam, with collision energies reaching 13.6 TeV in the LHC’s Run 3. Relativistic energy: E²=p²c²+m²c⁴. For highly relativistic particles, E≈pc. Lorentz factor: γ=1/√(1−v²/c²). Momentum: p=γmv. Magnetic bending: p=qBr. Proton charge: q=+e. Energy: E=γmc². LHC magnets use superconducting electromagnets. Proton beams travel in opposite directions and collide at interaction points. ATLAS, CMS, ALICE and LHCb study the collisions. Quantum mechanics: ΔxΔp≥ħ/2, E=hf, p=h/λ, iħ∂ψ/∂t=Ĥψ. Quantum field theory treats particles as excitations of fields. Standard Model: SU(3)C×SU(2)L×U(1)Y. Quarks: u,d,c,s,t,b. Leptons: e,μ,τ and their neutrinos. Gauge bosons: photon, gluons, W±, Z⁰. Higgs boson: excitation of the Higgs field. Strong interaction: QCD. Electromagnetism: QED. Weak interaction changes particle flavors and enables radioactive beta decay. Gluons mediate the strong interaction. Photons mediate electromagnetism. W and Z bosons mediate the weak interaction. Higgs mechanism gives mass to elementary particles through interactions with the Higgs field. Conservation laws: energy, momentum, angular momentum and electric charge. Relativistic invariant: s=E²/c²−p². Cross section measures interaction probability. Luminosity determines collision rate: R=Lσ. Antimatter has opposite quantum numbers such as electric charge. LHC experiments investigate the Higgs boson, quark-gluon plasma, antimatter, rare decays, CP violation, dark-matter candidates and possible physics beyond the Standard Model. The LHC does not recreate the Big Bang itself; it recreates extremely high-energy particle conditions similar to those existing in the early universe. General relativity: Gμν+Λgμν=(8πG/c⁴)Tμν. Quantum gravity remains unsolved.
