The effect is considered of high‐momentum plasmons on electrons in a 2D EG. It is found that the high‐momentum, low‐velocity plasmons can form electron‐plasmon pairs. Renormalizing the mass due to Coulomb interactions of these paired electrons, it is possible to explain very accurately the large mass shift measured in far‐infrared transmission experiments.
