An exceptionally light axion: Strong CP and Dark Matter
Pablo Quilez, Luca Di Luzio, Belen Gavela +1
We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The symmetry proposed by Hook, with $\ma…

An even lighter QCD axion
Luca Di Luzio, Belen Gavela, Pablo Quilez +1
We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The symmetry proposed by Hook, with $\ma…
