12. Improved constraints on Higgs self-couplings by including higher power dependence

健 王 (山东大学)

The precise determination of the Higgs boson self-couplings is essential for understanding the mechanism behind electroweak symmetry breaking. However, due to the limited number of Higgs boson pair events at the LHC, only loose constraints have been established so far.
Current constraints are based on the assumption that the cross section is a quadratic function of the trilinear Higgs...

32. NNLO corrections to $W$-pair and $H^+H^-$ production at CEPC

Dr Zhe Li (Shandong University)

After the discovery of the Higgs boson at LHC in 2012, the precision test of the SM and search for new physics beyond the SM have become two most important research areas in the field of high-energy particle physics. This presentation focuses on these two areas, providing an in-depth investigation of the NNLO mixed QCD-EW corrections to the production of the SM gauge boson pair and THDM...

31. Probing electroweak phase transition with gravitational waves

Shao-Jiang Wang (中国科学院理论物理研究所Institute of Theoretical Physics, Chinese Academy of Sciences)

The future space-borne gravitational wave (GW) detectors would provide a promising probe for the new physics beyond the standard model that admits the first-order phase transitions. The predictions for the GW background vary sensitively among different concrete particle physics models but also share a large degeneracy in the model buildings, which motivates an effective model description on...

11. Search for Higgs boson pair production with one associated vector boson in proton-proton collisions at $\sqrt{S} = 13 \mathrm{TeV}$ with the CMS experiment

立诚 章 (University of Maryland)

This study presents a search for a vector boson $V$ ($W$ or $Z$ boson) associated Higgs boson pair ($HH$) production process using proton-proton ($pp$) collision data at a center-of-mass energy of 13 TeV, collected by the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb$^{-1}$. The processes include $pp \rightarrow ZHH$ and $pp \rightarrow WHH$ production,...

2. Search for pair production of boosted Higgs bosons via vector-boson fusion in the bbbb final state using pp collisions at √s = 13 TeV with the ATLAS detector

Zhen Wang (University of Science and Technology of China (CN))

Ref. Phys. Lett. B 858 (2024) 139007
A search for Higgs boson pair production via vector-boson fusion is performed in the Lorentz-boosted regime, where a Higgs boson candidate is reconstructed as a single large-radius jet, using 140 fb−1 of proton-proton collision data at √s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Only Higgs boson decays into bottom quark pairs...

3. Search for triple Higgs boson production in the 6b final state using pp collisions at √s = 13 TeV with the ATLAS detector

Dr Jing Chen (SJTU/TDLI)

Ref. ATLAS-HIGP-2024-32
A search for production of three Higgs bosons (HHH) in the 6b final state is presented. The search uses 126 fb−1 of pp collision data at √s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis targets both non-resonant and resonant production of HHH. The resonant interpretations primarily consider a cascade decay topology of X→SH→HHH...
