7. Dark SHINE——Dark Photon fixed-target search experiment at SHINE Facility

Jing Chen (SJTU/TDLI)

01/08/2022, 14:40

This talk will present the R&D study of the prospect and feasibility to deploy the fixed-target experiment utilizing the high rate single electron beam from the SHINE facility under construction. The project is officially sponsored by NSFC Original Exploration Project 2021 and Shanghai pilot program for basic research.

18. Electroweak precision tests for triplet scalar

Huang Fei (SJTU)

Electroweak precision observables are fundamental for testing the standard model (SM) or its extensions. The influences on observables from new physics within the electroweak sector will be expressed in terms of oblique parameters S, T, U. By performing the global fit with the CDF new W mass, we obtain $S=0.03 \pm 0.03$, $T=0.06 \pm 0.02$ and $U=0.16 \pm 0.03$ or $S=0.14 \pm 0.03$, $T=0.24...

6. Search for HH-->4b production and H-->aa-->4b exotic decays with ATLAS and CEPC

Zhen Wang (TDLI/SJTU)

01/08/2022, 15:20

This talk will present the HH-->4b analysis result at ATLAS and also the exotic decays of 125GeV SM Higgs to light singlet scalar pairs in 4b final states with future circular colliders such as CEPC.

5. Search for Dark Higgs at ATLAS and potential to utilize the Xbb tagger

Changqiao LI (SJTU/TDLI)

01/08/2022, 16:00

This talk will present the latest searches for Mono-H125 and Mono-Scalar productions with SM and BSM Higgs at ATLAS, as a direct probe to BSM portal of new physics and especially Dark Matter. A potential of utilizing the boosted Xbb tagger will be also discussed.

3. Muon Electric Dipole Moment as a Probe of Flavor-Diagonal CP Violation

Yoshihiro Shigekami (Tsung-Dao Lee Institute)

Electric dipole moments (EDMs) of elementary particles are powerful probes of new physics with flavor-diagonal CP violation. The reported discrepancy in the muon anomalous magnetic moment motivates us to explore to what extent new physics with flavor-diagonal CP violation to address the discrepancy is probed by searches for the muon EDM. As a benchmark, we focus on a CP-violating...
