PENTAQUARK 04: Proceedings of the International Workshop, ...
The papers collected in this book represent an exciting contribution to the growing body of experimental and theoretical research into exotic hadrons. The prime focus of the volume is the latest work on pentaquark baryons.

A pentaquark, for instance, might be built from two up quarks, two down quarks,
and an antistrange quark. In 2003, Japanese experimenters at the Spring-8
accelerator near Osaka reported finding a bump in their data that could be
interpreted ...

Phenomenological Aspects of Heavy Quark Systems
If one turns off the potential which is identical for the heavy baryon and heavy
pentaquark states, and tune the baryon current coupling such that heavy baryons
are still bound with the appropriate binding energy, the heavy pentaquark
effective ...

Chiral Soliton Models for Baryons
Much of the ado around pentaquarks has been ignited by the prediction of a very
narrow pentaquark in [2]. Here we will illustrate that (ill)famed calculation
because we must address the question of whether it is a rigorous prediction of
chiral ...

5, the helicity asymmetry without the pentaquark is small, but recent work has
demonstrated that even such a small observable is measurable with high
precision at JLab 6. When the pentaquark is included in the calculation, this
observable ...

If we assume pentaquark production in e+e~ annihilation processes proceeds
through the creation of four qq pairs, this would yield a rate reduction of 10~8/
GeV/c2. Such a rapid drop in rate could make pentaquark production in e+c~ ...

The U-spin conservation may naturally account for this phenomenon, if the bump
is an indication of a hidden-strangeness pentaquark baryon N5(1670) in the anti-
decuplet state. PACS. 13.60.Le Meson production – 14.20.Dh Protons and ...

(64) Including all diagrams, the prediction for re is then 13 MeV (652 MeV) for a
positive (negative) parity pentaquark. In the CC case we get a width of 0.75 MeV (
37 MeV) for a positive (negative) parity pentaquark. The measured upper limit of
