One branch of physics named for two of these entities describes single and double resolved processes which result in the formation of a vector meson.
One branch of physics named for two of these entities describes single and double resolved processes which result in the formation of a vector meson. Their differential cross section is proportional to the square of the fine structure constant, and is given by the Klein-Nishina formula. Pair production describes their interaction with a (*) nucleus, creating a positron and an electron. The wavelength of one of these particles decreases in an effect named for the winner of the 1927 Nobel Prize in Physics, and is caused by their collision with electrons. For 10 points, identify these particles whose energy is decreased in Compton scattering, the quanta of light.
