Hi, this is my first post, and I'm sure this is a very basic question: Suppose two electrons collide, and thus momentum is conserved. Momentum, as we all know, is defined as the product of mass and velocity. But the means of transferring momentum between these electrons is a photon, which is...
Hi, All,
First time post, and this is quite possibly a very basic question: Is there a way to describe a particle's momentum such that the momentum itself is Lorentz invariant? The reason I am asking is this: As I understand it, if for example an electron and a positron were to collide and...
