New measurements in leptonic kaon and pion decays: experimental and theoretical perspectives
Lukas Allwicher, Stefan Alexandru Ghinescu, Federico Mescia +2
We study the future prospects for precision measurements of purely leptonic charged-current kaon and pion decays. In particular, we consider the single ratios $R_{Kπ}^{\ell=μ,e} =…

Could electron-top interactions spoil the measurement of the Higgs trilinear? -A quantitative estimate at future lepton colliders-
Lukas Allwicher, Christophe Grojean, Lucine Tabatt
The measurement of the Higgs self-coupling is considered the next milestone in the study of the Higgs boson properties. At future facilities below the double Higgs product…
