The $B^{+} \to K^{+} ν ν ˉ$ decay as a search for the QCD axion

Merna Abumusabh, Giulio Dujany, Diego Guadagnoli +2

We introduce a model-independent framework to reinterpret Belle II results using only public data, analytically reconstructing the mapping between true and reconstructed kinematic…

Probing a Light Scalar Boson with a few-MeV Proton Beam Deep Underground

Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2

We propose to investigate the production of a light scalar boson $ϕ$ in low-energy proton-nucleus interactions using the 3.5 MV accelerator of the Bellotti Ion Beam Facility, locat…

Gauged $τ$ -lepton chiral currents and $B \to K^{(*)} E_{miss}$

Luca Di Luzio, Marco Nardecchia, Claudio Toni

We consider a class of theories with a $U (1)_{X}$ gauge symmetry associated with leptonic chiral currents. The low-energy effective field theory includes a light spin- $1$ boson coupl…

Combined Evidence for the $X_{17}$ Boson After PADME Results on Resonant Production in Positron Annihilation

Fernando Arias-Aragón, Giovanni Grilli di Cortona, Enrico Nardi +1

The Positron Annihilation into Dark Matter Experiment at the Laboratori Nazionali di Frascati has reported an excess of $e^{+} e^{-}$ final-state events from positron annihilation on fi…

New bound on the vectorial axion-down-strange coupling from $K^{+} \to π^{+} ν ν ˉ$ data

Diego Guadagnoli, Axel Iohner, Cristina Lazzeroni +3

We reinterpret publicly available $K^{+} \to π^{+} ν ν ˉ$ data collected by NA62 from 2016 to 2024 to constrain the fundamental vectorial coupling of the QCD axion to down and strange…
