Axion quality from the (anti)symmetric of SU(N)
Marco Ardu, Luca Di Luzio, Giacomo Landini +3
We propose two models where a U(1) Peccei-Quinn global symmetry arises accidentally and is respected up to high-dimensional operators, so that the axion solution to the strong CP p…

Dark Matter in scalar Sp(N) gauge dynamics
Giacomo Landini, Jin-Wei Wang
We consider a model with Sp dark gauge group and a scalar field in the fundamental representation, which leads to two co-stable DM candidates at the perturbative level thanks to a…

Impact of Fermionic Electroweak Multiplet Dark Matter on Vacuum Stability with One-loop Matching
Jin-Wei Wang, Xiao-Jun Bi, Peng-Fei Yin +1
We investigate the effect of fermionic electroweak multiplet dark matter models on the stability of the electroweak vacuum using two-loop renormalization group equations (RGEs) and…
