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,...

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...

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...

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

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...

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

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...

102. Chasing 2HDM via electroweak corrections at e+e- colliders

Dr Yang Ma (UCLouvain)

Higgs Physics at Future Colliders

In this talk, I will present a comprehensive study of Higgs boson production associated with a neutrino pair at $𝑒^+𝑒^−$ colliders ($𝑒^+𝑒^−\to h\nu\bar{\nu}$) at NLO electroweak (EW) accuracy in both the SM and the two-Higgs-doublet model (2HDM). I will show that new physics effects from the extended Higgs sector can be probed through EW corrections, which lead to deviations from the SM...

115. Multiboson production at multi-TeV lepton colliders as complementary probes to rare Higgs decays

Arman Korajac (INFN Pisa)

29/10/2026, 12:10

We study the potential of very high-energy lepton colliders to constrain effective operators affecting the loop-induced Higgs decays $h \to \gamma \gamma $ and $h \to Z \gamma$, providing complementary measurements to such measurements at the Large Hadron Collider (LHC).
In particular, we consider processes with two and three bosons in the final state and analyze their individual and...
