Query: Light gravitino dark matter: LHC searches and Hubble tension   The recent measurements of the cosmological parameter $H_0$ from the direct
local observations and the inferred value from the Cosmic Microwave Background
show $\sim 4 \sigma$ discrepancy. This may indicate new physics beyond the
standard $\Lambda$CDM. We investigate the keV gravitino dark matter that has a
small fraction of non-thermal component (e.g. from the late decay of NLSP bino)
under various cosmological constraints. We find such a scenario is highly
predictive and can be tested by searching for the dilepton plus missing energy
events at the LHC. Besides, we also discuss its implication for Hubble tension,
however, which can be reduced to $3\sigma$ level marginally.
