Particle interactions are changes in the nature, number, or state of several particles, usually at a specific space-time point, underlying dynamics. They are represented by special "field interaction terms" in quantum field theory and normally entail interchanges of energy, momentum, and sundry quantum numbers. They include scattering, and particle creation and annihilation.

$2 \to 2$ scattering cross section in arbitrary theory
What is the general method to compute the $2 \to 2$ scattering cross section given an arbitrary Lagrangian ? I would like a step by step recipe that can be easily implemented in Mathematica.
For examp …

Deriving Feynman rules from generating functional $Z[J]$
I would like a general method to derive the Feynman rules for any scalar Lagrangian from the generating functional $$Z[J]=\int \mathcal{D}\phi \exp \left[iS[\phi]+i\int d^4xJ(x)\phi(x)\right].$$
