Descripción
The resonance at 125 GeV that has been discovered at the LHC has properties consistent with those of the Higgs particle in the Standard Model of electroweak interactions. Confirmation will await higher precision measurements. In this talk we will discuss some ideas on what one can do with high precision measurements. In particular we will briefly discuss the discriminating power of spectra, as opposed to integrated rates, in >2 body decays. And then we will discuss how perturbative unitarity a la Lee-Quigg-Thacker gives coupling constant sum rules and mass bounds for putative additional higgs particles, and will present some applications of these.
