Muon g-2 from Millicharged Hidden Confining Sector
Yang Bai, Seung J. Lee, Minho Son +1
We provide a novel explanation to the muon excess with new physics contributions at the two-loop level. In this scenario, light millicharged particles are introduced to modif…
Global Electroweak Symmetric Vacuum
Yang Bai, Seung J. Lee, Minho Son +1
Although the Higgs potential in the Standard Model (SM) contains only a simple electroweak symmetry breaking vacuum in the small field region, additional metastable or global vacua…
Cosmological Relaxation from Dark Fermion Production
Kenji Kadota, Ui Min, Minho Son +1
We consider the cosmological relaxation solution to the electroweak hierarchy problem using the fermion production as a dominant friction force. In our approach, neither super-Plan…
Leptogenesis in Cosmological Relaxation with Particle Production
Minho Son, Fang Ye, Tevong You
Cosmological relaxation of the electroweak scale is improved by using particle production to trap the relaxion. We combine leptogenesis with such a relaxion model that has no extre…
Constraints and Implications on Higgs FCNC Couplings from Precision Measurement of Decay
Cheng-Wei Chiang, Xiao-Gang He, Fang Ye +1
We study constraints and implications of the recent LHCb measurement of for tree-level Higgs-mediated flavor-changing neutral current (FCNC) interactions…
Towards gauge unified, supersymmetric hidden strong dynamics
Cheng-Wei Chiang, Sichun Sun, Fang Ye
We consider a class of models with extra complex scalars that are charged under both the Standard Model and a hidden strongly coupled gauge sector, and discuss the scenar…
Large Field Inflation from Axion Mixing
Gary Shiu, Wieland Staessens, Fang Ye
We study the general multi-axion systems, focusing on the possibility of large field inflation driven by axions. We find that through axion mixing from a non-diagonal metric on the…
Widening the Axion Window via Kinetic and Stückelberg Mixings
Gary Shiu, Wieland Staessens, Fang Ye
We point out that kinetic and Stückelberg mixings that are generically present in the low energy effective action of axions can significantly widen the window of axion decay consta…
Building a Stückelberg Portal
Wan-Zhe Feng, Gary Shiu, Pablo Soler +1
We construct explicit string theory models realizing the recently proposed "Stückelberg Portal" scenario, a framework for building Z' mediation models without the need to introduce…
Probing Hidden Sectors with Stückelberg U(1) Gauge Fields
Wan-Zhe Feng, Gary Shiu, Pablo Soler +1
We propose a framework in which visible matter interacts with matter from a hidden sector through mass mixings of Stückelberg U(1) gauge fields. In contrast to other Z' mediation s…
Milli-Charged Dark Matter in Quantum Gravity and String Theory
Gary Shiu, Pablo Soler, Fang Ye
We examine the milli-charged dark matter scenario from a string theory perspective. In this scenario, kinetic and mass mixings of the photon with extra U(1) bosons are claimed to g…
Soft branes in supersymmetry-breaking backgrounds
Paul McGuirk, Gary Shiu, Fang Ye
We revisit the analysis of effective field theories resulting from non-supersymmetric perturbations to supersymmetric flux compactifications of the type-IIB superstring with an eye…
Heavy Quark Expansion in 1/\hat{m}_Q and |V_{cb}| Extraction
Wen-Yu Wang, Yue-Liang Wu, Fang Ye
The dressed heavy quark mass \hat{m}_Q=m_Q+\bar{Λ} with \bar{Λ} being the binding energy is introduced to characterize the heavy hadrons containing a single heavy quark. A heavy qu…
