Search for light pseudoscalar bosons, pair-produced in Higgs boson decays in the four-electron final state in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for pairs of light neutral pseudoscalar bosons (A) resulting from the decay of a Higgs boson is performed. [...]

Differential decay rate of $B^+ \to J/\psi(\to \mu^+\mu^-) K^+$ with the LHCb Upgrade I experiment
The normalised decay rate of $B^+ \to J/\psi(\to \mu^+\mu^-) K^+$ is measured as a function of the lepton helicity angle using a data sample corresponding to an integrated luminosity of $1.1 \text{fb}^{-1}$ collected during October 2024 with the upgraded (Upgrade I) LHCb detector [...]

Search for Higgsinos in final states with low-momentum lepton-track pairs at 13 TeV / CMS Collaboration
We present a search for the pair production of Higgsinos in final states with large missing transverse momentum and either two reconstructed muons or a reconstructed lepton (muon or electron) and an isolated track. [...]
