Query: Bottomonium dissociation in a finite density plasma   We present a holographic description of the thermal behavior of $ b \bar b$
heavy vector mesons inside a plasma at finite temperature and density. The
meson dissociation in the medium is represented by the decrease in the height
of the spectral function peaks. In order to find a description for the
evolution of the quasi-states with temperature and chemical potential it is
crucial to use a model that is consistent with the decay constant behavior. The
reason is that the height of a spectral function peak is related to the value
of the zero temperature decay constant of the corresponding particle. AdS/QCD
holographic models are in general not consistent with the observation that
decay constants of heavy vector mesons decrease with radial excitation level.
However, it was recently shown that using a soft wall background and
calculating the correlation functions at a finite position of anti-de Sitter
space, associated with an ultraviolet energy scale, it is possible to describe
the observed behavior. Here we extend this proposal to the case of finite
temperature $T $ and chemical potential $\mu $. A clear picture of the
dissociation of bottomonium states as a function of $ \mu $ and $T$ emerges
from the spectral function. The energy scales where the change in chemical
potential leads to changes in the thermal properties of the mesons is
consistent with QCD expectations.
