Multi-hadron spectroscopy in a large physical volume

Hadron Spectroscopy

Perspectives in hadron spectroscopy 1

A brief survey is presented of selected recent results in hadron spectroscopy and related theoretical studies. This includes the pentaquarks and hadrons containing one or two charmed quarks or antiquarks.

Issues in Light Hadron Spectroscopy

A high priority in light spectroscopy is to seek out and characterize various types of non-(Q ¯ Q) meson. The large quantity of new data now appearing will present a great opportunity. To identify the non-(Q ¯ Q) intruders one needs to know the regular (Q ¯ Q) pattern well; whole meson families thus become a target for close investigation. A powerful discovery strategy is to observe the same me...

Exciting Developments in Hadron Spectroscopy

Heavy quark (c, b) spectroscopy is the best way of studying Quantum Chromodynamics, QCD. The |cc̄ > charmonium and |bb̄ > bottomonium states have several advantages over light quark (u, d, s) hadrons. The relativistic effects are much smaller, the strong coupling constant αS ≈ 0.2−0.3 is small enough to permit use of perturbative methods to a large extent, and the spectra consist of clearly separ...

Recent Issues in Hadron Spectroscopy *

During recent months, several new hadrons have been discovered or suggested in a variety of experiments, triggering renewed phenomenological and theoretical studies. The limits of the simple quark model have been reached and nowadays, understanding hadron spectroscopy requires chiral dynamics, coupling to decay channels, higher Fock configurations and, perhaps, explicit gluon degrees of freedom...
