Query: On the holographic dark energy in chameleon scalar-tensor cosmology   We study the holographic dark energy (HDE) model in generalized Brans-Dicke
scenario with a non-minimal coupling between the scalar field and matter
lagrangian namely Chameleon Brans Dicke (CBD) mechanism. In this study we
consider the interacting and non-interacting cases for two different cutoffs.
The physical quantities of the model such as, equation of state (EoS)
parameter, deceleration parameter and the evolution equation of dimensionless
parameter of dark energy are obtained. We shall show that this model can
describe the dynamical evolution of fraction parameter of dark energy in all
epochs. Also we find the EoS parameter can cross the phantom divide line by
suitable choices of parameters without any mines kinetic energy term.
