Baryoid Dark Matter from Domain Walls: The origin of the dark matter-baryon coincidence
Yang Bai, Ting-Kuo Chen
We propose an explanation for the dark matter-baryon coincidence based on collapsing domain walls, which form a novel compact baryonic state: the baryoid. A baryoid…
Toponia at the HL-LHC and FCC-ee
Yang Bai, Ting-Kuo Chen, Yiming Yang
The hint of a pseudoscalar toponium state at the Large Hadron Collider (LHC) opens a new avenue for studying a novel class of QCD (quasi-)bound states with comparable formation and…
Wess-Zumino-Witten Interactions of Axions: Three-Flavor
Yang Bai, Ting-Kuo Chen, Jia Liu +1
We present a complete Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three light-flavor quark framework. This formulation incorpora…
QCD Vacuum Energy and Its Implication for Quark Nugget Stability
Yang Bai, Ting-Kuo Chen
In this work, we employ both theoretical and data-driven methods to derive the QCD vacuum energy, utilizing the GMOR relation, the low-energy theorem, and the equation of state fro…
Approaching Stable Quark Matter
Yang Bai, Ting-Kuo Chen
The determination of whether the ground state of baryon matter in Quantum Chromodynamics (QCD) is the ordinary nucleus or a quark matter state remains a long-standing question in p…
Wess-Zumino-Witten Interactions of Axions
Yang Bai, Ting-Kuo Chen, Jia Liu +1
We present a consistent derivation of the complete Wess-Zumino-Witten interactions of axions, including the counter-term necessary to guarantee the gauge invariance of the Standard…
