Rise and Fall of Pentaquarks in the QCD Sum Rules Approach
نویسندگان
چکیده
We review the existing mass and decay width determinations of pentaquarks with QCD Sum Rules (QCDSR). We give special attention to the intermediate assumptions and choices which we are obliged to do in this approach. As an example, we present the full calculation of the pentaquark mass with Borel sum rules and also with Finite Energy Sum Rules (FESR). We also work out the calculation of the Θ decay width. We take the opportunity to comment our publications on this subject and include new and unpublished material.

S=+1 pentaquarks in QCD sum rules
Pentaquark states with strangeness S = +1 and IJπ = 0 2 ± ,1 1 2 ± ,0 2 ± ,1 2 ± are investigated using the QCD sum rule technique. Throughout the calculation, we emphasize the importance of the establishment of a valid Borel window, which corresponds to a region of the Borel mass, where the operator product expansion (OPE) converges and the presumed ground state pole dominates the sum rules. W...
متن کاملQCD Sum Rules of Pentaquarks
The spin and parity seem to be crucial to determine the structure of the pentaquarks. In the naive quark models, the ground state in which all the quarks occupy the lowest energy mode should have negative parity. We expect both the 1/2 or 3/2 states, whose splitting is given by the spin-spin interaction between quarks.[3,4] On the other hand, various model calculations predict a positive parity...
متن کاملTriquark correlations and pentaquarks in a QCD sum rule approach
The role of quark correlations in the description of hadron dynamics in many domains of physics, from low energy dynamics to very hot(dense) systems, is being appreciated. Strong correlations of two quarks (diquark) have been widely investigated in this respect. Recently, we have proposed a dynamical scheme to describe the Θ pentaquark in which also three quark correlations (triquark) were inst...

The objectives of this study is to investigate the responses of livestock economic variables (namely, output, consumption, prices, labor and capital) to changes in agricultural productivity, monetary, oil revenue and government spending (fiscal policy). To do so, a Dynamic Stochastic General Equilibrium (DSGE) model is constructed for Iran economy disaggregating livestock. Accordingly, the empi...
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...
