Extended Gauge Mediation in the NMSSM with Displaced LHC Signals
Marcin Badziak, Nishita Desai, Cyril Hugonie +1
We analyze models of extended Gauge Mediation in the context of the NMSSM, concentrating on supersymmetric spectra with light gluinos, low fine-tuning and decays of the lightest ne…
Faint Light from Dark Matter: Classifying and Constraining Dark Matter-Photon Effective Operators
Bradley J. Kavanagh, Paolo Panci, Robert Ziegler
Even if Dark Matter (DM) is neutral under electromagnetism, it can still interact with the Standard Model (SM) via photon exchange from higher-dimensional operators. Here we classi…
A Realistic U(2) Model of Flavor
Matthias Linster, Robert Ziegler
We propose a simple model of flavor compatible with an GUT structure. All hierarchies in fermion masses and mixings arise from powers of two small parameters that co…
Minimal Models for Dark Matter and the Muon g-2 Anomaly
Lorenzo Calibbi, Robert Ziegler, Jure Zupan
We construct models with minimal field content that can simultaneously explain the muon g-2 anomaly and give the correct dark matter relic abundance. These models fall into two gen…
A Grand-Unified Nelson-Barr Model
Jakob Schwichtenberg, Paul Tremper, Robert Ziegler
We argue that the Nelson-Barr solution to the Strong CP Problem can be naturally realized in an E Grand-Unified Theory. The chiral SM fermions reside in three generations of E$…
