We explore observational constraints on a cosmological model with an
interaction between dark energy (DE) and dark matter (DM), using a compilation
of 15 measurements of the 2D BAO (i.e., transversal) scale in combination with
Planck-CMB data, to explore the parametric space of a class of interacting DE
models. We find that 2D BAO measurements can generate different observational
constraints compared to the traditional approach of studying the matter
clustering in the 3D BAO measurements. Contrary to the observations for the
ΛCDM and IDE models when analyzed with Planck-CMB + 3D BAO data, we
note that Planck-CMB + 2D BAO data favor high values of the Hubble constant
H0. From the joint analysis with Planck-CMB + 2D BAO + Gaussian prior on
H0, we find H0=73.4±0.88 km/s/Mpc. We conclude that the H0
tension is solved in the IDE model with strong statistical evidence (more than
3σ) for the IDE cosmologies.Comment: 7 Pages, 2 Figures, 2 Tables. Matches the version published in PR
