Microscopic approaches to N\(\bar N\) annihilation potentials

Part of the Lecture Notes in Physics book series (LNP, volume 243)


The chiral quark models have given us a reasonable description of nucleons as a quark core surrounded by a meson cloud. When we scatter two nucleons we expect the large impact parameters to be dominated by meson exchanges. For nucleon-antinucleon scattering the same description is expected. However, for small impact parameters when the quark cores overlap, we expect annihilation to dominate. Therefore a study of the annihilation processes should give us information about the quark core in a nucleon. An attempt to calculate an N\(\bar N\) annihilation optical potential using chiral quark model properties will be discussed and we will show that the proton r.m.s. radius constrains the effective annihilation potential for N\(\bar N\) scattering.
