Higgs Couplings after the Discovery

Abstract

Following the ATLAS and CMS analyses presented around ICHEP 2012 we determine the individual Higgs couplings. The new data allow us to specifically test the effective coupling to photons. We find no significant deviation from the Standard Model in any of the Higgs couplings.

• Figure 1: $\Delta_W$ vs $\Delta_t$ for the expected SM measurements (left) and the actual measurements (right), assuming $m_H = 126$ GeV.
• Figure 2: Results based on 2011 and 2012 data, for the SM signal expectation and for the data ($m_H = 126$ GeV). We also show the form factor result $\Delta_H$ and universal fermion and boson couplings $\Delta_{V,f}$. The band indicates a $\pm 20\%$ variation.
