Model of the quintessence axion
Sudhakantha Girmohanta, Yu-Cheng Qiu, Jin-Wei Wang +1
We construct a model of the quintessence axion based on a gauged chiral symmetry and an additional flat fifth dimension. The required high qualities are guaranteed by the br…
High-quality axions in a class of chiral gauge theories
Yu-Cheng Qiu, Jin-Wei Wang, Tsutomu T. Yanagida
We show that there are many candidates for the quintessence and/or the QCD axions in a class of chiral gauge theories. Their qualities are high enough to serve as the dark e…
Electroweak Axion as the Fuzzy Dark Matter -- A Proposal for the Mixed Fuzzy and Cold Dark Matters
Yu-Cheng Qiu, Tsutomu T. Yanagida
The electroweak axion is identified with the fuzzy dark matter of a mass --. The model predicts two components of dark matter, one is ultralig…
Probing The Neutrino Sector via A Statistical Approach
Yu-Cheng Qiu, Hui-Yu Zhu
We apply the idea of landscape (motivated by string theory) to study the statistical nature of parameters/couplings in the standard model of strong and electroweak interactions. Fo…
Axi-Higgs Cosmology
Leo WH Fung, Lingfeng Li, Tao Liu +3
If the electroweak Higgs vacuum expectation value in early universe is higher than its present value GeV, the Li puzzle in BBN and the CMB/CDM tens…
Role of Bloch Waves in baryon-number violating processes
Yu-Cheng Qiu, S. -H. Henry Tye
In the Bloch-wave approach to estimate the baryon-number-violating scattering cross section in the standard electroweak theory in the laboratory, we clarify the relation between th…
