New Physics at Tera-$Z$: Precision Renormalised / Allwicher, Lukas (Zurich U.) ; McCullough, Matthew (CERN) ; Renner, Sophie (Glasgow U.)
We study the power of a Tera-$Z$ run at FCC-ee for indirectly detecting or constraining heavy new physics. [...]

Phenomenology of a Deconstructed Electroweak Force / Davighi, Joe (Zurich U. ; CERN) ; Gosnay, Alastair (Glasgow U.) ; Miller, David J. (Glasgow U.) ; Renner, Sophie (Glasgow U.)
We study an effective theory of flavour in which the $SU(2)_L$ interaction is `flavour-deconstructed' near the TeV scale. This arises, for example, in UV models that unify all three generations of left-handed fermions via an $Sp(6)_L$ symmetry. [...]

Prospects for $B_{c}^+\to \tau^+ \nu_\tau$ at FCC-ee / Amhis, Yasmine (IJCLab, Orsay) ; Hartmann, Marie (Orsay, LAL) ; Helsens, Clément (CERN) ; Hill, Donal (Ecole Polytechnique, Lausanne) ; Sumensari, Olcyr (IJCLab, Orsay)
This paper presents the prospects for a precise measurement of the branching fraction of the leptonic $B_{c}^+\to \tau^+ \nu_\tau$ decay at the Future Circular Collider (FCC-ee) running at the $Z$-pole. A detailed description of the simulation and analysis framework is provided. [...]

The first limit on invisible decays of $B_s$ mesons comes from LEP / Alonso-Álvarez, Gonzalo (McGill U. ; Toronto U.) ; Escudero Abenza, Miguel (CERN)
Motivated by the recent evidence for $B^+\to K^+\bar{\nu} \nu$ decays at Belle II, we point out that fully invisible $B_d$ and $B_s$ meson decays are strongly constrained by LEP. A reinterpretation of an old inclusive ALEPH search for $b$-hadron decays with large missing energy allows us to place the limits $\mathrm{Br}(B_d \rightarrow \mathrm{invisible}) < 1.4\times10^{-4}$ and $\mathrm{Br}(B_s \rightarrow \mathrm{invisible}) < 5.6\times10^{-4}$, both at $90\%$ CL.
