Query: Scalar-Connection Gravity and Spontaneous Scalarization   Scalar-tensor theories of gravity are known to allow significant deviations
from general relativity through various astrophysical phenomena. In this paper,
we formulate a scalar-connection gravity by setting up scalars and connection
configurations instead of metric. Since the matter sector is not
straightforward to conceive without a metric, we invoke cosmological fluids in
terms of their one-form velocity in the volume element of the invariant action.
This leads to gravitational equations with a perfect fluid source and a
generated metric, which are expected to produce reasonable deviations from
general relativity in the strong-field regime. As a relevant application, we
study spontaneous scalarization mechanism and show that the
Damour-Esposito-Far\`{e}se model arises in a certain class of scalar-connection
gravity. Furthermore, we investigate a general study in which the present
framework becomes distinguishable from the famed scalar-tensor theories.
