Query: Static spherically symmetric wormholes in generalized $f(R,\phi)$
  gravity   In this paper, we examine static spherically symmetric wormhole solutions in
generalized $f(R,\phi)$ gravity. To do this, we consider three different kinds
of fluids: anisotropic, barotropic and isotropic. We explore different
$f(R,\phi)$ models and inspect the energy conditions for all of those three
fluids. It is found that under some models in this theory, it is possible to
obtain wormhole solutions without requiring exotic matter. The discussion about
the conditions where the standard energy conditions (WEC and NEC) are valid for
the fluids is discussed in details. From our results and for our cases, we
conclude that for anisotropic and isotropic fluids, realistic wormhole
geometries satisfying the energy conditions can be constructed.
