CEPC Technical Design Report: Accelerator / CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar).

CEPC Conceptual Design Report: Volume 2 - Physics & Detector / CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large international scientific facility proposed by the Chinese particle physics community to explore the Higgs boson and provide critical tests of the underlying fundamental physics principles of the Standard Model that might reveal new physics.

Multi-component dark matter in the light of new AMS-02 data / Lai, Chang (Chongqing U.) ; Huang, Da (Taiwan, Natl. Tsing Hua U.) ; Geng, Chao-Qiang (Chongqing U. ; Taiwan, Natl. Tsing Hua U. ; NCTS, Hsinchu)
We study the possible positron/electron excesses within the multi-component leptonically decaying dark matter (DM) scenario by fitting the most recent AMS-02 data on the positron fraction and total e+ + e− flux. We show that both the single- and two-component DM models are able to fit the two AMS-02 datasets. [...]

Limit on Br(b --> sg) in two Higgs doublet models / Geng, Chao-Qiang (Taiwan, Natl. Tsing Hua U.) ; Turcotte, Paul (Taiwan, Natl. Tsing Hua U.) ; Hou, Wei-Shu (Taiwan, Natl. Taiwan U. ; CERN)
Using the recent CLEO measurement of $Br(b\to s \gamma)$, we find that the branching ratio of $b\to s g$ cannot be larger than $10\%$ in two Higgs doublet models. The small experimental value of $Br(b\to e\bar{\nu}X)$ can no longer be explained by charged Higgs boson effects..
