Light Fermionic WIMP Dark Matter with Light Scalar Mediator
Shigeki Matsumoto, Yue-Lin Sming Tsai, Po-Yan Tseng
A light fermionic weakly interacting massive particle (WIMP) dark matter is investigated by studying its minimal renormalizable model, where it requires a scalar mediator to have a…
New Emerging Results in Higgs Precision Analysis Updates 2018 after Establishment of Third-Generation Yukawa Couplings
Kingman Cheung, Jae Sik Lee, Po-Yan Tseng
We perform global fits of the Higgs boson couplings to all the 7 TeV, 8 TeV, and 13 TeV data available up to the Summer 2018. New measurements at 13 TeV extend to include the Higgs…
Phenomenology of A Little Higgs Pseudo-Axion
Kingman Cheung, Shi-Ping He, Ying-nan Mao +2
In models where the Higgs is realized as a pseudo-Nambu-Goldstone boson (pNGB) of some global symmetry breaking, there are often remaining pNGBs of some groups (called `pseu…
Muon g-2 and rare top decays in up-type specific variant axion models
Cheng-Wei Chiang, Michihisa Takeuchi, Po-Yan Tseng +1
The invisible variant axion models (VAM's) offer a very attractive solution for the strong CP problem without the domain wall problem. We consider the up-type specific variant axio…
violating mode of the stoponium decay into
Kingman Cheung, Wai-Yee Keung, Po-Yan Tseng
We show that a novel decay mode of the bound state of stop-anti-stop pair in the ground state may have a significant branching ratio if…
