New Excitation Mode of the Nucleon?

Nuclear Theory 2007-05-23 v2

Abstract

We consider properties of narrow baryon states observed recently in reaction pppπ+Xpp\to p\pi^+X. Two lowest of them (with mass 1004 and 1044 MeV, respectively) are stable against strog decay. Moreover we conclude that they cannot decay to γN\gamma N and thus this states are a kind of metastable levels in quark system. The simplest decay channel is assumed to be 2γN2\gamma N and possible quark configuration with such properties is discussed. New experiment for verification of status of this states in γN\gamma N collision is proposed.
