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 , that is experiments in which particle scatters off particle , possibly producing particles C_i in the process. 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 . The Breit frame is defined as the frame in which . There are different occasions when Breit frame can be useful, e.g., in measuring the electromagnetic form factor of a hadron, is the scattered hadron; while for deep inelastic scattering process, the elastically scattered parton should be considered as . It is only in the latter case the Breit frame gets related to infinite-momentum frame. It is named after the American physicist Gregory Breit.
