Updated monochromatization Interaction Region optics design for FCC-ee GHC lattice / Korsun, A (IJCLab, Orsay) ; Faus-Golfe, A (IJCLab, Orsay) ; Zhang, Z (IJCLab, Orsay) ; Zimmermann, F (CERN) ; Oide, K (U. Geneva (main) ; KEK, Tsukuba) ; Raimondi, P (Fermilab)
Determining Yukawa couplings of the Higgs boson is one of the most fundamental and outstanding measurements since its discovery. The FCC-ee, owing to its exceptionally high-integrated luminosity, offers the unique opportunity to measure the electron Yukawa coupling through s-channel Higgs production at 125 GeV centre-of-mass (CM) energy, provided that the CM energy spread can be reduced from 50 MeV to a level comparable to the Higgs bosons’ natural width of 4.1 MeV.

Optimized physics performance evaluation of monochromatization interaction region optics for direct $s$-channel Higgs production at FCC-ee / Zhang, Z (IJCLab, Orsay) ; Faus-Golfe, A (IJCLab, Orsay) ; Korsun, A (IJCLab, Orsay) ; d'Enterria, D (CERN) ; Zimmermann, F (CERN) ; Jiang, H (Lancaster U.

The measurement of electron Yukawa coupling ($y_{e}$) via direct $s$-channel Higgs production at $\sim$125 GeV centre-of-mass (CM) energy is significantly facilitated at the FCC-ee, provided that the CM energy spread can be reduced to a level comparable to the natural width of the Higgs boson. This reduction is possible through the “monochromatization” concept, which involves generating opposite correlations between spatial position and energy deviation in the colliding beams. [...]

High-energy hadron colliders with multi-TeV centre-of-mass energies require high-field superconducting magnets. Examples include the large hadron collider (LHC) and its high-luminosity upgrade (HL-LHC), as well as future projects such as the future circular collider (FCC-hh) and super proton–proton collider (SPPC).
