Exotic Electroweak Signals in Twin Higgs
Hsin-Chia Cheng, Ennio Salvioni, Yuhsin Tsai
The Twin Higgs model is the preeminent example of a theory of neutral naturalness, where the new particles that alleviate the little hierarchy problem are Standard Model (SM) singl…
Reconciling Large And Small-Scale Structure In Twin Higgs Models
Valentina Prilepina, Yuhsin Tsai
We study extensions of the Twin Higgs model that solve the Hierarchy problem and simultaneously address problems of the large- and small-scale structures of the Universe. Besides n…
Partially Acoustic Dark Matter, Interacting Dark Radiation, and Large Scale Structure
Zackaria Chacko, Yanou Cui, Sungwoo Hong +2
The standard paradigm of collisionless cold dark matter is in tension with measurements on large scales. In particular, the best fit values of the Hubble rate and the matter…
Faking SM Photons by Displaced Dark Photon Decays
Yuhsin Tsai, Lian-Tao Wang, Yue Zhao
A light meta-stable dark photon decaying into collimated electron/positron pair can fake a photon, either converted or unconverted, at the LHC. The detailed object identification r…
Gamma-rays from Dark Showers with Twin Higgs Models
Marat Freytsis, Simon Knapen, Dean J. Robinson +1
We consider a twin WIMP scenario whose twin sector contains a full dark copy of the SM hadrons, where the lightest twin particles are twin pions. By analogy to the standard WIMP pa…
