775. Search for Higgs boson pair production in the bbττ final state with ATLAS

莫岑

31/10/2026, 14:00

"Higgs boson pair production (HH) probes the Higgs boson self-coupling and the structure of the Higgs potential. This talk presents the ATLAS search for non-resonant HH production in the bbττ final state using the full Run 2 dataset and a partial Run 3 dataset.
The measured signal strength relative to the Standard Model (SM) prediction is $\mu_{HH}$ = 2.6, with uncertainties of +1.4 and −1.0,...

The study of non-resonant Higgs boson pair (HH) production provides direct sensitivity to the Higgs boson self-interaction. This talk presents an ongoing search for non-resonant HH production in multilepton final states using 140fb^-1 of ATLAS Run 2 data and 159fb^-1 of partial Run 3 data collected up to 2024. The analysis combines several complementary final states containing light leptons...

780. Search for nonresonant triple Higgs boson production in the final state with six bottom quarks in proton-proton collisions at √s = 13 TeV

"A search for nonresonant triple Higgs boson (HHH) production in the final state
with six bottom quarks is performed using proton-proton collisions at √s = 13 TeV
corresponding to an integrated luminosity of 138 fb−1 recorded by the CMS experi-
ment. No significant excess of events over the background prediction is seen. Ob-
served (expected) 95% confidence level upper limits on the signal...

781. Electroweak Corrections to Higgs Boson Pair Production in HEFT: Probing Cubic and Quartic Self-Couplings

Jia-Le Ding

31/10/2026, 15:30

We investigate electroweak corrections to gluon-fusion Higgs pair production in Higgs Effective Field Theory, allowing independent variations of the cubic and quartic self-couplings. We determine the complete self-coupling-dependent NLO cross-section coefficients and the NNLO terms quadratic in the quartic coupling. Combining these results with vector-boson-fusion predictions, we examine their...

923. Search for dark photons from Higgs boson decays in the gluon-gluon fusion channel in proton-proton collisions at √s=13.6 TeV with the ATLAS detector (online)

Tencent/VooV Meeting：620-331-282

This paper presents a search for semi-visible Higgs boson decays in final states with a photon ($\gamma$) and missing transverse momentum ($p_T^{miss}$). The analysis is optimised for the gluon-gluon fusion production channel and exploits a novel trigger deployed in 2023, with reduced thresholds down to 50 GeV on the photon transverse momentum ($p_T^\gamma$)...
