AbstractWe discuss the potential of the eXTP x-ray telescope, in particular its Spectroscopic Focusing Array, Large Area Detector and Wide Field Monitor for the detection of a signal from keV-scale decaying dark matter. We show that the sensitivity of the eXTP is sufficient to improve existing constraints on the mixing angle of the neutrino minimal extension of the Standard Model (nu MSM) by a factor of 5-10 within the dark matter mass range 2-50 keV, assuming 1% level of systematic uncertainty. We assert that the eXTP will be able to probe previously inaccessible range of nu MSM parameters and serve as a precursor for the Athena mission in decaying dark matter searches.
