The Yottascale at Tera-: Petascale SUSY?
Lukas Allwicher, Francisco N. C. Dahab, Christophe Grojean +2
As experimental and theoretical advances are made, the paradigm of grand unification faces growing challenges. In light of what has been learned at the LHC, from Higgs mass measure…

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. Together with the ratio of leptonic widths $R_K^ν=Γ(K\to eν)/Γ(K\t…

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…
