Relieving the Tension between Weak Lensing and Cosmic Microwave
  Background with Interacting Dark Matter and Dark Energy Models
  We constrain interacting dark matter and dark energy (IDMDE) models using a
450-degree-square cosmic shear data from the Kilo Degree Survey (KiDS) and the
angular power spectra from Planck's latest cosmic microwave background
measurements. We revisit the discordance problem in the standard Lambda cold
dark matter ($\Lambda$CDM) model between weak lensing and Planck datasets and
extend the discussion by introducing interacting dark sectors. The IDMDE models
are found to be able to alleviate the discordance between KiDS and Planck as
previously inferred from the $\Lambda$CDM model, and moderately favored by a
combination of the two datasets.
