Updated analysis of minimal supersymmetric SO(10) with a universal soft spectrum
Cheng-Wei Chiang, Takeshi Fukuyama
We update the analysis of minimal supersymmetric SO(10) grand unification with a universal, constrained-MSSM-like soft-breaking spectrum. A pair of Yukawa matrices in the ${\bf 10}…
Oblique corrections in general dark models
Cheng-Wei Chiang, Kazuki Enomoto
We investigate the impact of dark Abelian gauge bosons on the electroweak precision measurements at the one-loop level. The dark gauge boson couples to the standard model fermions…
Doubly charged Higgs boson at same-sign lepton colliders
Cheng-Wei Chiang, Kazuki Enomoto, Min-Yuan Liao
We investigate the search for doubly charged Higgs bosons in the Georgi-Machacek (GM) model at same-sign lepton colliders. The dominant production mode is vector boson fusion, thro…
Dark Z-mediated dark matter with verifiable exotic scalars
Chuan-Ren Chen, Cheng-Wei Chiang, Leon M. G. de la Vega
In this work, we study a dark matter scenario where a dark Z boson possessing mass mixing with the SM Z boson couples to the DM candidate and serves as the portal to the SM. The UV…
Flavor Physics at the CEPC: a General Perspective
Xiaocong Ai, Wolfgang Altmannshofer, Peter Athron +147
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is d…
Leptoquark-mediated Dirac neutrino mass and its impact on and decays
Chuan-Hung Chen, Cheng-Wei Chiang, Leon M. G. de la Vega
Right-handed neutrinos play a crucial role in flavor-changing neutral-current processes with missing energy, such as $b\to s + \slashed{E} $ and $d\to s + \slashed{E} $, whe…
