TI - Optics Design for a Monochromatization Scheme for the Direct S-Channel Higgs Production at FCC-ee Collider J2 - Proc. of eeFACT2022, Frascati, Italy, 12-16 September 2022 CY - Frascati, Italy T2 - ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders T3 - 65 LA - english AB - The FCC-ee collider baseline foresees four different energy operation modes: Z, WW, H(ZH) and ttbar. An optional fifth mode, called s-channel Higgs production mode, could allow the measurement of the electron Yukawa coupling, in dedicated runs at 125 GeV centre-of-mass energy, provided that the centre-of-mass energy spread, can be reduced by at least an order of magnitude (5-10 MeV). The use of a special collision technique known as monochromatization scheme (mono-scheme) is one way to accomplish it. The transverse monochromatization scheme consists of introducing a dispersion function different from zero but of opposite sign for the two colliding beams at the Interaction Point (IP); In this paper, we will report about the trade-off between energy spread and luminosity, and the first attempt to design a new optics to implement a transverse monochromatic scheme for the FCC-ee Higgs production.
