S711: How to Calculate a Feynman Diagram: Quantum Field Theory in Splash 2023 (Apr. 22, 2023)
Particle physics is a rich, but sometimes intimidating, branch of physics. You may have heard about a very common pictorial representation of particle interactions: Feynman diagrams. I aim to teach the following: 1. what is a quantum field 2. how a lagrangian describes a given quantum system 3. the Feynman ABCs 4. how to calculate Feynman amplitudes in the ABC theory. By the end, you will know how to evaluate and more importantly have an understanding behind equations like $$\int \int \int (-iq)^3 \frac{i}{q_4^2-m_B^2c^2} \frac{i}{q_5^2-m_A^2c^2} \frac{i}{q_6^2-m_C^2c^2} \cdot (2\pi)^4 \delta^4 (P_1 -q_4-P_3) (2\pi)^4 \delta^4 (q_4 -q_6-q_5) (2\pi)^4 \delta^4 (q_5 + q_6 -P_2) \cdot \frac{d^4 q_4}{(2\pi)^4}\frac{d^4 q_5}{(2\pi)^4}\frac{d^4 q_6}{(2\pi)^4}$$
