The Higgs Potential 2024 workshop, hosted by the University of Science and Technology of China (USTC), will take place from December 19 to 23, 2024, in Hefei.

This workshop is dedicated to advancing our understanding of the electroweak symmetry breaking mechanism. Key topics will include precise measurements of the Higgs boson’s properties, the search for double Higgs production, studies of Higgs self-coupling, and explorations of new physics beyond the Standard Model. Bringing together physicists from both theoretical and experimental backgrounds, the event aims to foster discussions on the latest advancements in Higgs physics and encourage collaborative efforts in the field.

14 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

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 are considered. The search is particularly sensitive to the quartic coupling between two vector bosons and two Higgs bosons relative to its Standard Model prediction, 𝜅2𝑉. This study constrains 𝜅2𝑉 to 0.55 < 𝜅2𝑉 < 1.49 at 95% confidence level. The value 𝜅2𝑉 = 0 is excluded with a significance of 3.8 standard deviations with other Higgs boson couplings fixed to their Standard Model values. A search for new heavy spin-0 resonances that would mediate Higgs boson pair production via vector-boson fusion is carried out in the mass range of 1-5 TeV for the first time under several model and decay-width assumptions. No significant deviation from the Standard Model hypothesis is observed and exclusion limits at 95% confidence level are derived.

15 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

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, considering all hadronic and leptonic decays of $V$ bosons involving electrons, muons, and neutrinos. The search focuses on the $b\bar{b}b\bar{b}$ decay channel of pairs of Higgs bosons. In our study, we set the upper limits for the $VHH$ production cross section at a 95\% confidence level. The observed (and expected) limits were found to be 294 (and 124) times the predictions of the standard model, respectively. Additionally, we conducted an evaluation of the modifiers of the Higgs boson trilinear self-coupling, denoted as $\kappa_\lambda$, and the coupling between two Higgs bosons and two vector bosons, represented by $\kappa_{2V}$. The confidence intervals at 95\% for $\kappa_\lambda$ were observed (expected) to be between $-37.7$ and $37.2$ ($-30.1$ and $28.9$), and for $\kappa_{2V}$, between $-12.2$ and $13.5$ ($-7.2$ and $8.9$), indicating the constraints placed on these parameters by our analysis.
