Hints of new physics in dark matter and neutrino sector and cosmological Hubble anomaly

Subinoy Das (IIA, Bangalore)

Abstract:The 5 sigma mismatch between CMB and local distance ladder measurements of Hubble parameter is one of the greatest challenge to our well known Lambda CDM model of cosmology. I will discuss that we definitely need beyond standard model particle physics to appear before CMB epoch if the anomaly persists. I will also discuss how secret dark matter decay or secret neutrino interaction can play a crucial role around CMB epoch to alleviate this recent problem in cosmology.
