Abstract
We predict several new exotic doubly heavy hadronic resonances, inferring from the observed exotic bottomoniumlike and charmoniumlike narrow states , , , , and . We interpret the binding mechanism as mostly molecularlike isospin-exchange attraction between two heavy-light mesons in a relative -wave state. We then generalize it to other systems containing two heavy hadrons which can couple through isospin exchange. The new predicted states include resonances in meson-meson, meson-baryon, baryon-baryon, and baryon-antibaryon channels. These include those giving rise to final states involving a heavy quark and antiquark , namely, , , , , , , , , , , , , , , and , as well as corresponding -wave states giving rise to or .
