Opening the Topological Portal to Dark Sectors with Colliders
Joe Davighi, Admir Greljo, Lia Schöneweiß +1
We study the phenomenology of the topological portal between QCD and pseudo-Nambu--Goldstone dark matter proposed in~\cite{Davighi:2024zip}. We construct a weakly coupled ultraviol…
Axion Quality from Exact Proton Stability
Joe Davighi, Admir Greljo, Xavier Ponce Díaz
A discrete, anomaly-free gauge symmetry may persist to the deep infrared, exactly forbidding proton decay. This can emerge from Higgsing a lepton-flavou…
Natural Phantom Dark Energy from a --Axion
Cédric Delaunay, Admir Greljo
We present a technically natural microscopic realization of apparent phantom dark energy based on an axion coupled to copies of two-flavor dark QCD related by a …
Hierarchies from Higher Flavor Spin
Admir Greljo, Alessandro Valenti
We develop a framework in which Yukawa hierarchies arise from powers of fully anarchic spurions transforming in higher representations of the flavor symmetry group $SU(2)^{n_2}\tim…
When Two Loops Matter: Electroweak Precision in the SMEFT
Lukas Born, Admir Greljo, Anders Eller Thomsen
We identify a novel next-to-leading order renormalization effect in the dimension-six SMEFT with direct phenomenological impact. The Higgs-Yukawa operator that modifies the top-Hig…
Charting the Flavour Structure of Dark Matter
Simone Biondini, Admir Greljo, Xavier Ponce Díaz +1
What flavour structure of -channel thermal dark matter remains compatible with current flavour physics and direct detection bounds? We broadly chart the space of hypotheses usin…
