Exotic Pion Like States as "Infra-red" Regge Trajectories & a New View about Nuclear Physics

Abstract

There is considerable evidence for what might be called "infrared" Regge trajectories having having interpretation in terms of string with string tension considerably lower than hadronic string tension. This article was motivated by a finding new evidence for pion like state in the decays of long-lived kaon. The discussion of these findings  leads to a more detailed formulation of nuclear string model in terms of IR Regge trajectories of nucleons allowing to understand the successes of harmonic oscillator model but with totally different interpretation. Also the nuclear binding energy can be understood at rather quantitative level in the model. Nuclear physics would reduce to that for the magnetic body of nucleon.
