Quantum Field Theory Calculator
Explore fundamental concepts of quantum field theory including scattering amplitudes, vacuum energy density, and propagator corrections. This calculator provides simplified models to analyze particle interactions, field fluctuations, and quantum corrections in both natural and SI units.
Formulas Used
- Scattering Amplitude: M ∝ α / (2 (1 − cosθ))
- Differential Cross Section: dσ/dΩ ∝ |M|²
- Vacuum Energy Density: ρ ≈ Λ⁴ / (16π²) + m²Λ² / (8π²)
- Self-Energy (Propagator): Σ ≈ λm² / (16π²)
- Natural Units: ℏ = 1, c = 1
