Quintessence Axion Dark Energy and a Solution to the Hubble Tension

20 Apr 2020 Choi Gongjun Suzuki Motoo Yanagida Tsutomu T.

We present a model in which the question about a nature of the dark energy and the recently raised Hubble tension can be addressed at once. We consider the electroweak axion in the minimal supersymmetric standard model where the axion energy density is identified with the observed dark energy... (read more)
