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…
Constraining off-shell production of axion-like particles with and differential cross-section measurements
Sonia Carra, Vincent Goumarre, Ruchi Gupta +6
This article describes a search for low-mass axion-like particles (ALPs) at the Large Hadron Collider (LHC). If ALPs were produced at the LHC via gluon-gluon fusion and decayed to…
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…
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…
