(1) Is it true that when a pair of particles is created from a Photon, that the Photon Energy (h x nu) is equal to 2(msub0)c^2 ?(adsbygoogle = window.adsbygoogle || []).push({});

If say an electron and positron are created does the photon Energy equal (at least) twice the mass of one electron 2(9.109 x 10^-31 kg)times c^2?

(2) Could anyone recommend the best Text Book that I should get if I want to study Yang-Mills Equations and Gauge Groups ? Is Group Theory in Real Analysis Textbooks?
