Dark top partner
Haiying Cai, Giacomo Cacciapaglia
Composite Higgs models with extended symmetries can feature mesonic dark matter candidates. In fundamental CHMs, the origin of dark parity can be explained in the UV theory. Combin…
Radion dynamics in multibrane Randall-Sundrum model
Haiying Cai
The radion in the Randall-Sundrum model is stabilized by the back reaction of a bulk scalar field with its VEV depending on the fifth dimensional coordinate. We studied the radion…
Partial compositeness under precision scrutiny
Haiying Cai, Giacomo Cacciapaglia
We revisit the impact of top partial compositeness on electroweak precision observables in the misaligned vacuum basis. We identify a new source for in the singlet mixing case,…
Effective Lagrangian and stability analysis in warped space
Haiying Cai
In the warped space model, the inter-brane distance can be stabilized by the Goldberger-Wise mechanism. Of particular importance, the stabilization potential calls for a proper ide…
Massive Gravitons as Feebly Interacting Dark Matter Candidates
Haiying Cai, Giacomo Cacciapaglia, Seung J. Lee
We detailed our discovery of a chiral enhancement in the production cross sections of massive spin-2 gravitons, below the electroweak symmetry breaking scale, that makes them ideal…
A Singlet Dark Matter in the SU(6)/SO(6) Composite Higgs Model
Haiying Cai, Giacomo Cacciapaglia
Singlet scalar Dark Matter can naturally arise in composite Higgs models as an additional stable pseudo-Nambu-Goldstone boson. We study the properties of such a candidate in a mode…
