New Heavy Exotic Hadrons
We review recent studies on exotic states at the Belle experiment. The results include: (1) The measurement of the cross sections of γγ → ωφ , φφ , and ωω for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin-zero and spin-two charmonium states, there are clear resonant structures below charmonium threshold, which have not been previously observed. W...
متن کاملNew Exotic Meson and Baryon Resonances from Doubly Heavy Hadronic Molecules.
We predict several new exotic doubly heavy hadronic resonances, inferring from the observed exotic bottomoniumlike and charmoniumlike narrow states X(3872), Z_{b}(10610), Z_{b}(10650), Z_{c}(3900), and Z_{c}(4020/4025). We interpret the binding mechanism as mostly molecularlike isospin-exchange attraction between two heavy-light mesons in a relative S-wave state. We then generalize it to other ...
متن کاملFrustration-induced exotic properties of magnetic molecules
Geometric frustration of interacting spin systems is the driving force of a variety of fascinating phenomena in lowdimensional magnetism. In this contribution I will review recent results on frustration-induced effects in magnetic molecules, i.e. zero-dimensional magnetic systems, as well as in a recently synthesized frustrated molecule-based spin tube, i.e. a one-dimensional spin system. c © 2...
متن کاملScattering of Heavy Stable Exotic Hadrons
The observation of exotic stable massive particles (SMPs) with electric, magnetic or colour charge (or combinations thereof) would be of fundamental significance. Searches are therefore routinely made for SMPs bound in matter, and for SMPs at cosmic ray and collider experiments [1, 2, 3, 4]. Furthermore, SMPs with masses at the TeV scale are anticipated in a number of beyond-the-Standard-Model ...
متن کاملPair Production of Heavy-Exotic-Fermions
We study the production and signatures of heavy exotic fermion pairs in the framework of the vector singlet model (VSM), vector doublet model (VDM) and fermion-mirror-fermion (FMF) model. We show that the pair production cross sections are competitive with the ones for the single production of exotic fermions due to the exchange of a photon in the s channel and to the vector component of the Z ...
