Query: The Spectrum of a Binding System for a Heavy Quark with an Anti-Sbottom
  or for a Sbottom and Anti-Sbottom Pair   Since long-lived light bottom squark (sbottom) and its anti-particle with a
mass close to the bottom quark have not been excluded by experiments so far, we
consider such a sbottom to combine with its anti-particle to form a color
singlet meson-like bound state or to combine with a common anti-quark to form a
fermion-like one, or accordingly their anti-particles to form an anti-particle
bound system. Namely we calculate the low-lying spectrum of the systems based
on QCD inspired potential model. To be as relativistic as possible, we start
with the framework of Bethe-Salpeter (BS) equation even for non-relativistic
binding systems. Finally, we obtain the requested spectrum by constructing
general forms of the BS wave functions and solving the BS equations under
instantaneous approximation.
