Crossing SNe Ia and BAO observational constraints with local ones in
  hybrid metric-Palatini gravity
  In this paper, we consider the recently proposed hybrid metric-Palatini
gravitational theory, which consists of adding to the Einstein-Hilbert
Lagrangian an $f(\mathcal{R})$ term constructed \`{a} la Palatini. Using the
respective dynamically equivalent scalar-tensor representation, we explore the
cosmological evolution of a specific model, given by $f(\mathcal{R}) \propto
\mathcal{R}^2$, and obtain constraints on the free parameters by using
different sources of cosmological data. The viability of the model is analysed
by combining the conditions imposed by the Supernovae Ia and Baryonic Acoustic
Oscillations data and the results are compared with the local constraints.
