abstract

We discuss the theory and phenomenology of $B_{d,s}\to V(\to M_1M_2)\ell\ell$ decays in the presence of neutral-meson mixing. We derive expressions for the time-dependent angular distributions for decays into CP eigenstates, and identify the relevant observables that can be extracted from time-integrated and time-dependent analyses with or without tagging, with a focus on the difference between measurements at $B$-factories and hadronic machines. We construct two observables of interest, which we call $Q_8^-$ and $Q_9$, and which are theoretically clean at large recoil. We compute these two observables in the Standard Model, and show that they have good potential for New Physics searches by considering their sensitivity to benchmark New Physics scenarios consistent with current $b\to s\ell\ell$ data. These results apply to decays such as $B_d\to K^*(\to K_S\pi^0)\ell\ell$, $B_s\to \phi (\to K_SK_L)\ell\ell$ and $B_s\to \phi(\to K^+K^-)\ell\ell$.

  1. Searches for $B^0\to K^+\pi^-\tau^+\tau^-$ and $B_s^0\to K^+K^-\tau^+\tau^-$ decays

    hep-ex 2025-10 accept novelty 8.0 of 10

    LHCb reports the first upper limits on B0 → K+π−τ+τ− and Bs0 → K+K−τ+τ− branching fractions, with recast limits of 2.8×10−4 on B0 → K*(892)0 τ+τ− at 95% CL that improve prior bounds by an order of magnitude.

  2. Time-Dependent Precision Measurement of $B_s^0\rightarrow \phi \mu^+\mu^-$ Decay at FCC-$ee$

    hep-ph 2025-06 conditional novelty 6.0 of 10

    FCC-ee could measure B_s -> phi mu+ mu- branching ratio to 0.5% and time-dependent CP observables D_f, C_f, S_f to 0.1, 0.02, and 0.02, giving order-of-magnitude better Wilson coefficient constraints than pre-FCC projections.

  3. Investigating non-local contributions in $B_{s} \to \phi \bar{\ell} \ell$ including higher-twist effects

    hep-ph 2025-02 conditional novelty 6.0 of 10

    Including twist-5 and twist-6 B_s-meson distribution amplitudes enhances the charm-loop non-local form factors in B_s to phi l+l- by about an order of magnitude, producing a larger but still Standard-Model-consistent ...
