Analyzing the Mesonic Spectrum Using the Method of Schottky Anomaly

摘要

64.1 Introduction The search for exotic hadrons has been rejuvenated in recent years with the discovery of the so called "pentaquark states" [1]. Along with the X, Y, Z states [2] discovered in the last decade by the different experimental groups [3] and the recent confirmation of the Λ(1405) as a molecular state [4] (which had been proposed earlier [5]), this has rekindled the quest for a better theoretical understanding of these states. Various models have been proposed to this end over decades [6]. We propose a model independent analysis in order to identify states which differ in their underlying dynamics due to different interaction scales responsible for forming composite mesonic states using the method of Schottky anomaly.
