One of the important ways in which the Higgs boson was detected at the Large Hadron Collider was by observing a type of decay in which the Higgs—which decays too quickly to be observed directly—is immediately transformed into two photons emitted back to back. Two photons, with momenta , were detected. What is the mass of the Higgs boson? Give your answer as a multiple of the proton mass.

The mass of the Higgs boson is

We have given two photons, with momenta

We need to find the mass of the Higgs boson.

Consider:

Using formula:

Calculating from equation (1)

Now, finding the Higgs boson :

(Substitute value in the equation )

Mass of the Higgs boson is given as :
