    New physics models such as Z' models or EWIMPs (via loop contribution) can be probed by the precise measurements of 2-fermion final states at Higgs factories and measuring dependence on fermions, polarization and angles can enhance the possibility of searching and identifying those models. We are studying qq and ll final states with 500 GeV ILC using ILD full simulation. The analysis methods...

  2. 26. Experimental prospects for indirect BSM searches in $e^{+}e^{-}\rightarrow q\bar{q}$ ($q=c,b$) processes at Higgs Factories.

    Future Higgs Factories will allow the precise study of $e^{+}e^{-}\rightarrow q\bar{q}$ with 𝑞$q=s,c,b,t$ interactions at different energies, from the Z-pole to high energies never reached before.
    In this contribution, we will discuss the experimental prospects for the measurement of differential observables in $e^{+}e^{-}\rightarrow b\bar{b}$ and $e^{+}e^{-}\rightarrow c\bar{c}$ processes at...

  3. 44. Flavor, Colliders, and the Z-pole: Opportunities for probing new physics at FCC-ee

    Any new physics (NP) lying at the TeV scale must pass stringent flavor as well as collider bounds. Since the top Yukawa gives the largest quantum correction to the Higgs mass, one well-motivated expectation is TeV-scale NP dominantly coupled to the third family. This setup delivers U(2) flavor symmetries that allow one to start explaining flavor at the TeV scale, while simultaneously improving...

  4. 69. Flavor changing Higgs and Z decays at FCC-ee [zoom]

    In this talk, we assess the FCC-ee reach for $Z/h\to bs, cu$ decays as a function of jet tagging performance. Recent advances in $b$, $c$, and $s$ quark tagging coupled with novel statistical analysis techniques allow the FCC-ee to place phenomenologically relevant bounds on flavor violating Higgs and $Z$ decays to quarks. We also update the SM predictions for the corresponding branching...
