Heavy quark symmetry in multihadron systems. Yamaguchi, Y., Ohkoda, S., Hosaka, A., Hyodo, T., & Yasui, S. Phys. Rev. D, 91(3):34034, American Physical Society, feb, 2015. ![Heavy quark symmetry in multihadron systems [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex We discuss the properties of hadronic systems containing one heavy quark in the heavy quark limit. The heavy quark symmetry guarantees the mass degeneracy of the states with total spin and parity (j-1/2)P and (j+1/2)P with j≥1/2, because the heavy quark spin is decoupled from the total spin j of the light components called brown muck. We apply this idea to heavy multihadron systems and formulate the general framework to analyze their properties. We demonstrate explicitly the spin degeneracy and the decomposition of the wave functions in exotic heavy hadron systems generated by the one-boson-exchange potential. The masses of the brown muck can be extracted from theoretical and experimental hadron spectra, leading to the color nonsinglet spectroscopy.
