The mass splitting and the decay width of pentaquark ( + ) at the higher angular momentum states have been investigated in the framework of flux tube model considering the diquark-diquark-antiquark configuration for + along with statistical model. A quasi particle model for diquark has been considered. The Regge trajectory of + has also been investigated with interesting some observations. Keywords Exotic particle · Quasiparticle · Decay width · Regge trajectory · Mass spectrum Diakonov et al. theoretically proposed the low mass (1530 MeV) and total decay width ( < 15 MeV) of + baryon in the framework of chiral soliton model [1] denoting the exotic baryon as a pentaquark state. The LEPS collaboration [2] reported the first experimental evidence of a sharp baryon resonance peak at 1540 ± 10 MeV with a width smaller than 25 MeV whereas, SAPHIR [3] detector detected the resonance peak at 1540 ± 4 ± 2 MeV with < 25 MeV at 90 percent c.l. ZEUS collaboration [4] reported the experimental existence of pentaquark ( + ) suggesting the mass to be 1521.5 ± 1.5 MeV and decay width 6.1 ± 1.6 MeV whereas CLAS collaboration [5,6] suggested the value to be 1555 ± 10 MeV and decay width ≤ 26 MeV. Since LEPS collaboration reported the existence of + resonance several groups confirm the state whereas a number of experiments gives null result. The next generation of experiments have been taken by JLAB, CLAS for further search.The theoretical states of + has been studied by Doi [7] in the direct QCD calculation. The low lying states of this exotic baryon have been investigated in the context of pseudoscalar vector skryme model by . Diakonov [9] has made a mean field approach to study the pentaquark excitation using SU(3) flavor symmetries. Iwasaki

We study the interesting problem of interaction and identification of the hadronic molecules which seem to be deuteron-like structure. In particular, we propose a binding mechanism in which One Boson Exchange Potential plus Yukawa screen-like potential is applied in their relative s-wave state. We propose the dipole-like interaction between two color neutral states to form a hadronic molecule. For the identification of the hadronic molecules, the Weinberg's compositeness theorem is used to distinguish the molecule from confined (elementary) state. The present formalism predict some di-hadronic molecular states, involving quarks (s, c, b or s, c, b) as a constituents, namely, pn, KK, ρρwith their possible quantum numbers.
