The Nelson-Barr Relaxion
Oz Davidi, Rick S. Gupta, Gilad Perez +2
Cosmological relaxation models in which the relaxion is identified with the QCD axion, generically fail to account for the smallness of the strong CP phase. We present a simple alt…
New LHC bound on low-mass diphoton resonances
Alberto Mariotti, Diego Redigolo, Filippo Sala +1
We derive a new bound on diphoton resonances using inclusive diphoton cross section measurements at the LHC, in the so-far poorly constrained mass range between the Upsilon and the…
R-axion at colliders
Brando Bellazzini, Alberto Mariotti, Diego Redigolo +2
We study the effective theory of a generic class of hidden sectors where supersymmetry is broken together with an approximate R-symmetry at low energy. The light spectrum contains…
The Axiflavon
Lorenzo Calibbi, Florian Goertz, Diego Redigolo +2
We show that solving the flavor problem of the Standard Model with a simple flavor symmetry naturally leads to an axion that solves the strong CP problem and constitutes a…
