Pentaquark states in a chiral potential
Atsushi Hosaka ;
Date 18 Jul 2003
Journal Phys.Lett. B571 (2003) 55-60
Subject hep-ph
AbstractWe discuss a possible interpretation for the pentaquark baryon $Theta^+$ which has an exotic quantum number of strangeness $S = +1$. The role of the pion which modifies the structure of single-particle levels of quarks is examined. When the pion field is sufficiently strong, the ground state of five quarks for $Theta^+$ acquires positive parity. If this is the case, an excited state may appear slightly above the ground state with negative parity.
