Pentaquarks: Status and Perspectives for Lattice Calculations
نویسنده
چکیده
The quantum chromo-dynamics (QCD) may not preclude the presence of the multi-quark hadrons such as tetraquark (qqq̄q̄), pentaquark (qqqqq̄), dibaryon (qqqqqq) and so on, because of the color confinement. Especially, we are let to be interested in exotic multi-quark hadrons, which should have exotic quantum numbers. Now, let us address ourself to the pentaquark state. Consider the SU(3) flavor case. Pentaquark states should form six different multiplets:

Looking for pentaquarks in Lattice QCD
Pentaquark states in lattice QCD probably lie close in energy to two particle scattering states. Correctly identifying the resonant state is a challenging, yet tractable, problem given the terascale computing facilities available today. We summarize the initial round of exploratory lattice calculations and discuss what should be accomplished in the next round.

Motivated by the possible observation of the Θ+(1530), we study the quark structure of pentaquark states in quenched lattice QCD. The complete set of 19 local sources that have the proper symmetry for positive or negative parity isoscalar pentaquarks is constructed, as well as a nonlocal source composed of two displaced “good” diquarks. Quantitative structure information is determined from diag...
متن کاملHadronic Physics and Exotics
I report on the state of hadronic physics and spectroscopy as reflected in contributions to the HEP2005 Europhysics Conference. Topics of interest include lattice field theory calculations of the hadron spectrum, the continuing quest to account for the proton’s spin, pentaquarks, high-statistics Dalitz-plot analyses, excited charmed–strange mesons, quarkonium spectroscopy, and the new levels as...
متن کاملA Review of Pentaquark Calculations on the Lattice
The recent interest in pentaquark baryons has been inspired by the experimental discovery of Θ(1540) whose quark composition is uudds̄. We will not address the experimental situation. It is summarized by T. Nakano in his plenary talk during this conference 1. In the past few years, there has been quite an effort to calculate these pentaquark states to see if they can be observed in lattice QCD c...
متن کاملPentaquark Baryons in String Theory -talk at Pentaquark 04-
Pentaquark baryons Θ and Ξ−− are studied in the dual gravity theory of QCD in which simple mass formulae of pentaquarks are derived in the Maldacena prototype model for supersymmetric QCD and a more realistic model for ordinary QCD. In this approach it is possible to explain the extremely narrow decay widths of pentaquarks. With the aim of constructing more reliable mass formulae, a sketch is g...
