Abstract
We use the most recent data on the Higgs-like resonance h observed at 125 GeV to derive information about the mass of the heavier Higgs particles predicted by Minimal Supersymmetry. We treat as independent parameters the couplings of h to top quark, beauty and massive vector bosons and, in this three-dimensional space, we locate the point realizing the best fit to data and compare it to the position of the Standard Model point and to the region of coupling values accommodating heavier Higgs particles in Minimal Supersymmetry. We conclude that mass values 320≲MH≲360 GeV are compatible at 2σ with the best fit of couplings to present data, larger values being compatible at the 1σ level. Values of 1≲tanβ≲6 are compatible with data.

We treat as independent parameters the couplings of h to top quark, beauty and massive vector bosons and, in this three dimensional space, we locate the point realizing the best fit to data and compare it to the position of the Standard Model point and to the region of coupling values accommodating heavier Higgs particles in Minimal Supersymmetry
In a recent paper [1], we confronted Minimal Supersymmetry for the Higgs sector with the particle discovered by ATLAS and CMS at 125 GeV
The presence of a tenuous bump at about 320 GeV in the CMS data for the ZZ channel could have been taken as a hint of the heavier, Minimal Supersymmetric Standard Model (MSSM), 0+ Higgs particle, H
Summary
We treat as independent parameters the couplings of h to top quark, beauty and massive vector bosons and, in this three dimensional space, we locate the point realizing the best fit to data and compare it to the position of the Standard Model point and to the region of coupling values accommodating heavier Higgs particles in Minimal Supersymmetry. GeV, We study the problem in the (ct, cb, cW ) space of couplings of the h resonance to the top and beauty quarks and to the vector bosons, ci representing the ratios of the MSSM to the Standard Model (SM) couplings.
