## Inferring the Nature of the Boson at 125-126 GeV

The Higgs boson is believed to have been discovered at the Large Hadron
Collider. The task now is not only to verify accurately whether the boson
is indeed the scalar Higgs as proposed in the Standard Model of particle
physics but to study its properties in detail. We present a step by step
methodology to determine the properties of this resonance without making any
assumptions about its couplings. We present the analysis in terms of
measurements that would require the minimum number of events. We show that
by studying the three uni-angular distributions and other readily measurable
observables, one can unambiguously confirm whether the new boson is indeed
the Higgs with J^{PC} = 0^{++} and with couplings to Z bosons exactly as
predicted in the Standard Model. We also show how possible deviations in
the couplings of Higgs to vector bosons can be observed.
