Breit frame

In particle physics, the Breit frame (also known as infinite-momentum frame or IMF) is a frame of reference used to describe scattering experiments of the form

[1] The frame is defined so that the particle A has its momentum reversed in the scattering process.

Another way of understanding the Breit frame is to look at the elastic scattering

There are different occasions when Breit frame can be useful, e.g., in measuring the electromagnetic form factor of a hadron,

It is named after the American physicist Gregory Breit.
