Distributin of photon virtuality

Manojg · 2012-06-25T23:49:26+00:00

Hi guys, Does anybody know good references for the distribution of virtual photon, i.e. Q2 distribution, in eletro-production with fixed electron energy on a fixed target? Thanks PS: title should be "distribution of virtual photon"

Thread 'How Can Photons Be Massless Yet Have Energy According to Einstein's Equations?'

Since E = mc^2, how can photons be massless? If a photon has no mass, then, according to Einstein's formula, its energy is given by E = 0 x c^2, which is 0. Yet, photons do have energy. This seems to be a complete contradiction. Please explain! Thank you.
