Hi,

How can a photon interact with a electron (ex. Compton scattering) whether the photon has no sign like positive ou negative charges?

How the field (EM wave) in the photon interact with a electron ?

Diagram of Compton scattering: an incident photon with wavelength λi hits a target electron at rest, which recoils at angle φ while the scattered photon with wavelength λf leaves at angle θ. Formula: λf − λi = Δλ = (h / m0c)(1 − cosθ).
