In quantum electrodynamics, Bhabha scattering is the electron-positron scattering process:
There are two leading-order Feynman diagrams contributing to this interaction: an annihilation process and a scattering process. The Bhabha scattering rate is used as a luminosity monitor in electron-positron colliders.
Bhabha scattering is named after Indian physicist Homi J. Bhabha
