Query: Global monopole as a generator of a bulk-brane structure in Brans-Dicke
  bulk gravity   We investigate a braneworld model generated by a global monopole in the
context of Brans-Dicke gravity. After solving the dynamical equations we found
a model capable to alleviate the so-called hierarchy problem. The obtained
framework is described by a hybrid compactification scheme endowed with a
seven-dimensional spacetime, in which the brane has four non-compact dimensions
and two curled extra dimensions. The relevant aspects of the resulting model
are studied and the requirements to avoid the well known seesaw-like behavior
are discussed. We show that under certain conditions it is possible to
circumvent such a pathological behavior that characterizes most of the models
that exhibit hybrid compactification. Lastly, we deepen our analysis by
considering possible extensions of this model to a setup with multiple branes
and orbifold-like extra dimension. For this, we compute the consistency
conditions to be obeyed by this more general configuration as predicted by the
braneworld sum rules formalism. This study indicates the possibility of
exclusively positive brane tensions in the model.
