Notes: Abstract Hybrid mesons composed of a quark, an antiquark, and a gluon are studied in the case of heavy quarks. Their masses are calculated with the potential model which can interpret heavy quarkonium spectroscopy. The ground state of the hybrid mesons $$c\bar cg$$ and $$b\bar bg$$ is found to be almost spherically symmetric, whereas that of $$t\bar tg$$ is two-centered as anH 2 + molecule. The $$b\bar bg\left[ {t\bar tg} \right]$$ ground state turns out to have a mass below the $$B\bar B\left[ {T\bar T} \right]$$ threshold. The excited states contain 0−−, 1−+ exotic states and 1−− states which may be examined bye + e − colliders.
