Introduction: what is quantum field theory ?
... Yet another reason to treat fields as the fundamental physical quantity is that all particles of the same type are the same. This is much more serious than it initially sounds. For example, two electrons are identical in every way, regardless of where they came from and what they’ve been through. Th ...

leading quantum correction to the newtonian potential
... When starting from the Einstein action, the divergences appear at higher order, i.e., in α, β for one loop, and in γ at two loops. This is not hard to see on dimensional grounds; the expansion is in powers of κ2 q 2 ∼ Gq 2 which forms a dimensionless combination. These divergences can be absorbed in ...
