Today's focus:

[CEPC Neutral Triple Gauge Couplings (nTGC) in the Zννˉγ Channel]:

• Writing the simulation part of the paper draft, here is the summary of this part:
  • The study targets the EFT sensitivity to 9 nTGC operators at CEPC.
  • The signal cross section is parameterized as SM + interference + quadratic terms; in 2D, an additional operator-mixing cross term is included.
  • Signal samples are generated with MadGraph + Pythia8 and simulated with CEPCSW.
• Current task: redo the 2D fit for the EFT operator coefficients and optimize the scan range to obtain more sensible confidence contours.

[ZZy]:

• Studied the paper and the supporting note, and now have a clearer understanding of the physics goal and the main analysis strategy of this project.

Plans:

CEPC:

• Continue the 2D fit optimization for the EFT operator coefficients.
• Help Yuning investigate the "0 hit" issue in the e+e−→ννˉγ MC samples generated by MadGraph in the full simulation chain (sim, tracking, digi, and reco).

ZZy:

• Discuss the next concrete steps of the project with Matthias tomorrow
