ALP contribution to the Strong CP problem
Victor Enguita, Belen Gavela, Benjamin Grinstein +1
We compute the one-loop contribution to the -parameter of an axion-like particle (ALP) with CP-odd derivative couplings. Its contribution to the neutron electric dipole mome…
On discrete Goldstone bosons
Victor Enguita-Vileta, Belen Gavela, Rachel Houtz +1
Exact discrete symmetries, if non-linearly realized, can reduce the ultraviolet sensitivity of a given theory. The scalars stemming from spontaneous symmetry breaking are massive w…

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…
Dark matter from an even lighter QCD axion: trapped misalignment
Luca Di Luzio, Belen Gavela, Pablo Quilez +1
We show that dark matter can be accounted for by an axion that solves the strong CP problem, but is much lighter than usual due to a symmetry. The whole mass range…
