The study of exotic hadrons in lattice QCD∗
نویسنده
چکیده
Recent studies of exotic hadrons from lattice QCD simulations are briefly reviewed. Hybrid bgb molecules in which the heavy bb pair is bound together by the excited gluon field g are investigated using the Born-Oppenheimer expansion and quenched numerical simulations. The consistency of results from the two approaches reveals a simple and compelling physical picture for heavy hybrid states. Results for the mass of the light-quark exotic meson from recent simulations are listed. These results agree with each other, but are significantly higher than the current experimental candidate.

Exotic Mesons, Hadrons and the Electro-Strong Interaction
Exotic Mesons and Hadrons are high energy states of Quark oscillations. Taking into account the Planck Distribution Law of the electromagnetic oscillators, we can explain the electron/proton mass rate and the Weak and Strong Interactions. Lattice QCD gives the same results as the diffraction patterns of the electromagnetic oscillators, explaining the color confinement and the asymptotic freedom...
متن کاملPentaquarks: Status and Perspectives for Lattice Calculations
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...
متن کاملGlueballs and Hybrids (Gluons as Constituents)
In addition to the familiar baryons made from three quarks and mesons made from a quark and an antiquark, the spectrum of QCD is expected to contain glueballs, hybrids and multiquark states. Since the earliest lattice QCD calculations it has been recognized that lattice QCD should be used to calculate the properties of these particles. Hopefully, lattice results will help to sort out which of t...
متن کاملLattice Predictions for Hybrids and Glueballs
QCD is a simple elegant theory, but it is hard to solve it using anything other than perturbation theory. Quantities, such as masses, depend on the coupling (g) like M ∼ e 2 [1], hence perturbation theory can’t be used to compute the masses of hadrons such as the proton. Our inability to solve QCD non-perturbatively makes it hard to determine basic parameters of the quark sector of the standard...

In the Hadronic interactions, the point which is less considered is the mass effect of interacting Hadrons on the energy distribution function of outgoing Hadrons. In this article we present a method to incorporate these mass effects which leads us to improve one of the basic formulas in QCD. In the end, we will show how these mass effects improve our previous results.
