Description
In this poster a sensitivity study of detecting sterile keV neutrinos in tritium beta decay will be presented. Relic sterile neutrinos in the keV range are classical candidates for the so-called Warm Dark Matter. They can explain mass distributions in the sub-galactic scale and thereby resolve the tensions in purely Cold Dark Matter scenarios, while being consistent with observations of the large scale structures.
This work shows that from a purely statistical point of view a future KATRIN-like experiment can reach a sensitivity of a mixing angle down to sin2Q ~ 10-8, probing the cosmologically favored parameter space. We investigate the effect of theoretical and experimental uncertainties using different analysis techniques based on spectral fits, covariance matrix approach and discrete wavelet transform.
