Equation Name & Description: What Is It?

In summary, an equation is a mathematical statement that shows the relationship between two or more variables and typically contains numbers, symbols, and mathematical operations. It differs from a formula in that it describes the relationship between variables, while a formula is a specific mathematical rule or procedure used to solve a problem or obtain a result. The purpose of an equation is to describe a mathematical relationship between variables and solve problems or find unknown values. Some common types of equations include linear, quadratic, polynomial, and trigonometric equations. In science, equations are used to describe and predict natural phenomena, model physical systems, and analyze and interpret data. They are a crucial tool for understanding and explaining the world around us.

Could someone tell me what the attached equation is called, and just and brief description of what it states. I don't recognise it and it's hard to know where one goes to just look up an equation.

Thanks

That's the differetial cross section being equal to the absolute value squared of the scattering amplitude. Look up "quantum scattering".
