2. Geant4 Simulation of Cherenkov Light Production in Plastic Scintillators for Fast Beam Diagnostics in Precision Higgs Experiments

Handan YILMAZ (İstanbul Technical University)

Higgs Physics at Future Colliders

Precision measurements in Higgs physics at the LHC and future collider facilities require highly stable beam conditions, accurate detector-response characterization, and fast diagnostic systems. In this context, plastic scintillators provide attractive candidates for compact and radiation-tolerant monitoring devices, while their Cherenkov component may offer additional timing-sensitive...

52. Higgs boson couplings and total width at FCC-ee

Ang Li (Brookhaven National Laboratory (US))

Higgs Physics at Future Colliders

The FCC-ee programme is uniquely positioned to determine the fundamental properties of the Higgs boson with unprecedented precision. At centre-of-mass energies of 240 and 365 GeV, FCC-ee will produce millions of Higgs bosons through Higgsstrahlung, complemented by a sizeable WW-fusion sample at 365 GeV. The clean experimental environment and the known initial state allow a model-independent...

10. Higgs prospect studies from ATLAS experiment

Reisaburo Tanaka (IJCLab, Université Paris-Saclay (FR))

Higgs Physics at Future Colliders

Higgs physics will be a main focus of the energy frontier of particle physics at future colliders. This talk summarizes the Higgs prospect studies from ATLAS experiment.

67. On the Phenomenology of a Real Inert Singlet-Triplet Dark Matter Model at current and future colliders

Jonas Scheibler (DESY)

Higgs Physics at Future Colliders

We present a comprehensive phenomenological study of a real inert singlet-triplet dark matter model. This model extends the Standard Model (SM) with 2 inert scalars: a gauge-singlet and a hypercharge-zero SU(2)_L-triplet. Our analysis takes into account state-of-the-art theoretical and experimental constraints. A central focus of our work lies on beyond-the-SM (BSM) two-loop corrections to key...

101. Physical Interpretation of SMEFT Effects in single boson productions at TeV-Scale Lepton Colliders

Hiroyuki Furusato

Higgs Physics at Future Colliders

We demonstrate that the Feynman-Diagram gauge provides a transparent decomposition of SMEFT contributions according to scattering mechanisms and gauge-higgs interaction vertices, enabling a direct physical interpretation of Wilson-coefficient effects in electroweak scattering.
Building upon this framework, we perform feasibility studies for future TeV-scale lepton colliders (ILC, FCC-ee, Muon...

66. Precision Higgs physics at FCC-hh

Birgit Stapf (CERN)

Higgs Physics at Future Colliders

The FCC-hh, colliding protons at a centre-of-mass energy of 84 TeV, will produce single and double Higgs boson samples orders of magnitude larger than those available at the LHC. This unprecedented statistics will enable few-percent precision on rare decays such as H→μμ, H→γγ, and H→Zγ, a stringent test of the top Yukawa coupling through ttH production, and a direct measurement of the Higgs...

53. The Higgs boson mass and the electron Yukawa coupling at FCC-ee

Ang Li (Brookhaven National Laboratory (US))

Higgs Physics at Future Colliders

Precise knowledge of the Higgs boson mass opens the door to one of the most ambitious opportunities of the FCC-ee programme: resonant s-channel Higgs production at √s = mH. At √s = 240 GeV, the recoil mass of Higgsstrahlung events with leptonic Z decays determines mH from purely kinematic information, independently of the Higgs decay. Recent studies project a precision at the few-MeV level,...
