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…
Flavor constraints on electroweak ALP couplings
M. B. Gavela, R. Houtz, P. Quilez +2
We explore the signals of axion-like particles (ALPs) in flavor-changing neutral current (FCNC) processes. The most general effective linear Lagrangian for ALP couplings to the ele…
Axion couplings to electroweak gauge bosons
G. Alonso-Álvarez, M. B. Gavela, P. Quilez
We determine the model-independent component of the couplings of axions to electroweak gauge bosons, induced by the minimal coupling to QCD inherent to solving the strong CP proble…
Color Unifed Dynamical Axion
M. K. Gaillard, M. B. Gavela, R. Houtz +2
We consider an enlarged color sector which solves the strong CP problem via new massless fermions. The spontaneous breaking of a unified color group into QCD and another confining…
Gauging Lepton Flavour
P. Quilez
The flavour lepton symmetry is gauged for both the Standard Model flavor group and its extension with three degenerate right-handed neutrinos. As a consequence of anomaly cancellat…
