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). [...]

Hadron collider probes of the quartic couplings of gluons to the photon and $Z$ boson / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Ge, Shao-Feng (Shanghai Jiaotong U. ; Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiao Tong U.) ; Ma, Kai (Shanghai Jiaotong U. ; Tsung-Dao Lee Inst., Shanghai ; HIAS, UCAS, Hangzhou ; ICTP-AP, Beijing ; Shaanxi U. Tech.)
We explore the experimental sensitivities of measuring the $gg \rightarrow Z \gamma$ process at the LHC to the dimension-8 quartic couplings of gluon pairs to the $Z$ boson and photon, in addition to comparing them with the analogous sensitivities in the $gg \to \gamma \gamma$ process. These processes can both receive contributions from 4 different CP-conserving dimension-8 operators with distinct Lorentz structures that contain a pair of gluon field strengths, $\hat G^a_{\mu \nu}$, and a pair of electroweak SU(2) gauge field strengths, $W^i_{\mu \nu}$, as well as 4 similar operators containing a pair of $\hat G^a_{\mu \nu}$ and a pair of U(1) gauge field strengths, $B_{\mu \nu}$.

Probing the Scale of New Physics in the $ZZ\gamma$ Coupling at $e^+e^-$ Colliders / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn ; Tsung-Dao Lee Inst., Shanghai) ; Ge, Shao-Feng (Tsung-Dao Lee Inst., Shanghai ; Tokyo U., IPMU ; UC, Berkeley ; Shanghai Jiaotong U.) ; He, Hong-Jian (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiaotong U. ; Tsinghua U., Beijing ; Peking U., CHEP) ; Xiao, Rui-Qing (Tsung-Dao Lee Inst., Shanghai ; Shanghai Jiaotong U.)
The $ZZ\gamma$ triple neutral gauge couplings are absent in the Standard Model (SM) at the tree level. They receive no contributions from dimension-6 effective operators, but can arise from effective operators of dimension-8. [...]

Constraining Gluonic Quartic Gauge Coupling Operators with $gg \to \gamma \gamma$ / Ellis, John (CERN ; King's Coll. London ; NICPB, Tallinn) ; Ge, Shao-Feng (Tokyo U., IPMU ; UC, Berkeley)
Gluon-gluon to photon-photon scattering $gg \to \gamma\gamma$ offers to the LHC experiments a uniquely powerful probe of dimension-8 operators in the Standard Model Effective Field Theory (SMEFT) that are quadratic in both the electromagnetic and gluonic field-strength tensors, such as would appear in the Born-Infeld extension of the Standard Model (SM). We use 13-TeV ATLAS data on the production of isolated photon pairs to set lower limits on the scales of dimension-8 operators $M \gtrsim 1$~TeV, and discuss the prospective sensitivities of possible future hadron colliders..
