Higgs boson self-coupling constraints from single Higgs, double Higgs and Electroweak measurements

Giuseppe Degrassi, Biagio Di Micco, Pier Paolo Giardino +1

We set constraints on the trilinear Higgs boson self-coupling, ${\lambda }_3$, by combining the information coming from the $W$ mass and leptonic effective Weinberg angle, electroweak preci…
