$C\!P$ violation analysis of local and nonlocal amplitudes in the $\overline{B}^0 \to \overline{K}^{*0}μ^+μ^-$ decay / LHCb Collaboration
A search for $C\!P$ violation in the $\overline{B}^0 \to \overline{K}^{*0}μ^+μ^-$ decay is performed using proton--proton collision data collected by the LHCb experiment during Run 1 and Run 2, corresponding to an integrated luminosity of 8.4 fb$^{-1}$. [...]

Lepton Flavor Violating Higgs decays at the Compact Linear Collider / Garay Walls, Francisca (Pontifical Catholic University of Chile (CL)) ; Vega Hernandez, Gabriel Andres (CERN) ; Roloff, Philipp Gerhard (CERN)
Lepton flavor violating Higgs decays could appear in scenarios beyond the Standard Model of particle physics. In this article, we study the sensitivity of a future Compact Linear Collider (CLIC) to such processes, namely, $h\rightarrow e\mu$, $h\rightarrow\tau\mu$, and $h\rightarrow e\tau$. [...]

Evidence for the decay $B_s^0\to \phi \eta^\prime$ / LHCb Collaboration
Using a dataset corresponding to an integrated luminosity of $9 \,\textrm{fb}^{-1}$ collected in proton-proton collisions between 2011 and 2018 by the LHCb experiment, evidence is found for the decay $B^0_s\rightarrow\phi\eta'$ with $3.5 \sigma$ significance. [...]

Continuum contribution to charged-current absorption of low-energy $ν_e$ on $^{40}$Ar / Gardiner, Steven (Fermilab) ; Barham Alzás, Pablo (CERN) ; Nikolakopoulos, Alexis (Washington U., Seattle ; Gent U.) ; El-Haj, Luca H Abu (Fermilab ; Columbia U.) ; Jachowicz, Natalie (Gent U.) ; Pandey, Vishvas (Fermilab)
Accurate modeling of the absorption of tens-of-MeV $ν_e$ on $^{40}$Ar is needed to enable measurements of astrophysical neutrinos using large liquid argon time projection chamber (LArTPC) detectors, such as those planned for the Deep Underground Neutrino Experiment (DUNE). [...]
