Can Y0*(1405) be a Bound State of Three Quarks?

  • G. Rajasekaran


Two approaches have been used so far to understand the observed hadron spectrum: a) to regard any observed hadron as a composite (bound or resonant) formed by forces between other observed hadrons, and b) to consider the observed hadrons as bound states of some sofar-unobserved heavy quarks. In the former (bootstrap model) the forces are calculated from exchanges of the known hadrons between the known hadrons and then the positions and widths (or coupling constants) of the composites are predicted. In the latter (quark model) one postulates some forces between the quarks and predicts the spectrum of quark bound states. Successes have been claimed in both these approaches.
