 Luminosity (scattering theory)

In the context of scattering theory in quantum mechanics, "luminosity" usually refers to a measure of the number of potential scattering events per unit area per unit time. It is often used in high-energy particle physics and collisions in accelerator experiments. To elaborate: 1. **Definition**: Luminosity (L) is defined in terms of the number density of particles (n) in the colliding beams and the relative velocity (v) of the colliding particles.
