Description
Talks are 17' (presentation) + 5' (discussion)
Parallel room, 20 Washington Place
The extensive and ambitious physics program planned for the Future Circular Collider for electrons and positrons (FCC-ee) demands exceptional detector performance. This talk systematically investigates how different detector configurations impact jet flavor identification and their effects on high-profile physics analyses. Using Higgs boson coupling measurements and searches for invisible...
The High-Luminosity LHC (HL-LHC) is expected to deliver an integrated dataset of approximately 3 ab⁻¹, enabling detailed studies of Higgs boson processes with unprecedented precision. Projections based on current analyses have been performed to estimate the expected measurement accuracy and identify potential limitations. The large data sample will also significantly enhance sensitivity to...
The title says it all
Precise predictions for Higgs decays are crucial for new physics searches. Possible deviations from the Standard Model (SM) can be investigated in a model-independent way by using the Standard Model Effective Field Theory (SMEFT). We present the complete set of predictions for the 2- and 3- body Higgs decays at next-to-leading order (NLO), considering QCD and electroweak corrections and...
The FCC-ee offers powerful opportunities to determine the Higgs boson parameters, exploiting about 2*10^6 e+e-→ZH events and almost 10^5 WW→H events at centre-of-mass energies around 240 and 365 GeV. The determination of the Higgs boson mass with a precision significantly better than the Higgs boson width (4.1 MeV in the Standard Model) is a prerequisite to either constrain or measure the...
The Higgs boson provides a unique window into new physics, and a high-energy muon collider offers an unparalleled environment to explore this potential. In this talk, I will discuss how a dedicated forward muon detector can be leveraged to probe BSM physics in the Higgs sector. Detecting forward muons allows us to efficiently search for invisible Higgs decays and heavy states that couple to...
The Higgs mechanism is a cornerstone of the Standard Model, and its self-coupling is a key parameter for experimental verification. Double-Higgs production provides tree-level sensitivity to the trilinear self-coupling and becomes measurable at sufficiently high center-of-mass energies. At 550 GeV in electron–positron collisions, the dominant channel is di-Higgs strahlung, with a smaller...

The FCC-ee programme is uniquely positioned to provide unprecedented precision on the fundamental properties of the Higgs boson. At the center-of-mass energies 240 and 365 GeV, the FCC-ee will produce millions of Higgs bosons via Higgs-strahlung and vector boson fusion. The clean experimental environment allows a model-independent measurement of the absolute ZH cross-section to better than...
The FCC-hh, operating at a centre-of-mass energy of 84 TeV, will produce unprecedentedly large samples of single and double Higgs bosons, enabling detailed studies of rare decays and precise measurements of the Higgs self-coupling. With billions of single-Higgs events, FCC-hh will measure rare decays such as H→μμ, H→γγ, and H→Zγ with percent-level precision. It will also significantly enhance...
