abstract
A first search for the lepton-flavour violating decays $B^0 \to K^{*0} \tau^\pm \mu^\mp$ is presented. The analysis is performed using a sample of proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV between 2011 and 2018, corresponding to an integrated luminosity of 9 fb$^{-1}$. No significant signal is observed, and upper limits on the branching fractions are determined to be ${\cal{B}}(B^0 \to K^{*0} \tau^+ \mu^-)< 1.0$ $(1.2)\times 10^{-5} $ and ${\cal{B}}(B^0 \to K^{*0} \tau^- \mu^+)< 8.2$ $(9.8) \times 10^{-6}$ at the 90% (95%) confidence level.

Comprehensive ALP Searches in Meson Decays
A new open-source tool, ALPaca, computes axion-like particle constraints from meson decays and finds that only the non-universal DFSZ model with large tan beta can explain the Belle II B+ to K+ plus missing energy exc...

Constraints on lepton-flavor mixing with third-generation new physics
The U(2)_ℓ-breaking spurion δ is constrained to |δ| < 0.051 (95% CL) by R_K(*) and B_s→μμ data, with derived upper limits for LFV τ and B decays.

Features of Charged Lepton Flavor Violation in an $A_4$ Symmetric Neutrino Mass Model
A reanalysis of an A4 neutrino mass model concludes meson CLFV decays can be near current bounds while radiative CLFV vanishes, but the radiative amplitude is computed incorrectly.
