Nucleon‐nucleon interactions and quarks: Isospin violations arising from quark interchange

Abstract

We have developed a formalism for describing isospin violations in nucleon‐nucleon interactions. It is emphasized that quark interchange, or percolation, gives rise to isospin‐violating effects in nucleon‐nucleon interactions. it is also pointed out that such isospin violation studies allow us to distinguish percolation effects from other categories of new physics.
