Answer to Question #11650 in Quantum Mechanics for Joanna

Question

The higgs boson has a mass of aprox 126.5 Ge/V^2.
How can the higgs boson have mass if it is the particle that gives things mass. Do higgs bosons always come in pairs so that they interact with each other to give each other mass?
And how do higgs bosons interact with massive objects? i.e., what particles do they exchange? Like two electrons exchange photons, doesn't a higgs particle and a massive object have to exchange some particles too? Do they exchange strings as in string theory?

Thank you very much for any replies :)
