Recent experimental evidence for the Theta^+(1540) has given rise to much theoretical interest in exotic baryons. The Theta^+ is a baryon that has strangeness S=+1, meaning that it contains an anti-strange quark. Thus it cannot be constructed from three quarks, unlike all other known baryons; it needs at least an extra quark-antiquark pair. It is usually modeled as a pentaquark state in the 10 bar representation of flavor SU(3), with flavor content \bar{s}uudd. This thesis considers possible… Expand

Negative parity pentaquarks in large N(c) QCD and quark model
Recently, the 1/N{sub c} expansion has been applied to the study of exotic baryons containing both quarks and antiquarks. We extend this approach to exotic states with mixed-symmetric spin-flavorExpand
The anticharmed exotic baryon Θ c and its relatives
Motivated by the recent discovery of the exotic S = +1 narrow baryon resonance Θ+ at 1540 MeV, with quark content uud ds̄, we conjecture the existence of its anti-charmed analogue Θcwith quarkExpand
Pentaquark Theta+, constituent quark structures, and prediction of charmed Theta0(c)and bottomed Theta+(b)
The newly observed $\Theta^+$ resonance is believed to be a pentaquark with the constituent quarks $uudd\bar s$. There are a few options for the constituent quark structure. Some advocateExpand
The Constituent quark model revisited: Quark masses, new predictions for hadron masses and KN pentaquark
Prompted by the recent surprising results in QCD spectroscopy, we extend to heavy flavors the hadron mass relations showing that the constituent quark mass differences and ratios have the same valuesExpand
How to search for pentaquarks in high energy hadronic interactions
The strange-anticharmed Pentaquark is a uudc̅s or uddc̅s five-quark baryon that is expected to be either a narrow resonance, or possibly even stable against strong and electromagnetic decay. WeExpand
A model realisation of the Jaffe-Wilczek correlation for pentaquarks
We discuss a realisation of the pentaquark structure proposed by Jaffe and Wilczek within a simple quark model with colour-spin contact interactions and coloured harmonic confinement, whichExpand
Penta-quark baryon in anisotropic lattice QCD
The penta-quark(5Q) baryon is studied in anisotropic quenched lattice QCD with renormalized anisotropy a_s/a_t=4 for a high-precision mass measurement. The standard Wilson action at beta=5.75 and theExpand
Radial excitations of low–lying baryons and the Z+ penta–quark
Abstact: Within an extended Skyrme soliton model for baryons the interplay between the collective radial motion and the SU(3)–flavor–rotations is investigated. The coupling between these modes isExpand
A schematic model for pentaquarks based on diquarks
Abstract QCD instantons are known to produce deeply bound diquarks which may be used as building blocks in the formation of multiquark states, in particular, pentaquarks and dibaryons. We suggest aExpand
1/N expansion for exotic baryons
The 1/N c expansion for exotic baryons is developed, and applied to the masses, meson couplings and decay widths. Masses and widths of the 27 and 35 pentaquark states in the same tower as the ??+ areExpand
