Finger-printing the new boson
Determine its ‘profile’:
• Mass
• Width
• Spin
• CP nature
• Coupling to fermions
• Coupling to gauge bosons
• Yukawa coupling to top quark
• Self coupling Higgs potential

Finger-printing the Higgs boson
Is it:
the Higgs Boson of the Standard Model?
another type of Higgs boson?
something that looks like a Higgs boson but is actually more complicated?

Finger-printing the Higgs boson
Is it:
the Higgs Boson of the Standard Model?
another type of Higgs boson?
something that looks like a Higgs boson but is actually more complicated?
Measurements of the Higgs couplings to the different species of quarks, leptons and gauge bosons are the key to answering these questions
