Why do you say that? Because now theorists say it is?
The paper says "if you assume a SM Higgs, and nothing else, there are no inconsistencies". The experiments have been saying that since...um...about July 4th.
"If you assume a SM W, and nothing else, there are no inconsistencies".
"If you assume a SM top, and nothing else, there are no inconsistencies". Well, the forward-backward asymmetry at Tevatron.
We have the same status for all known particles. Sure, the W-boson has more measured parameters, but that is just a quantitative difference, not a qualitative.
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.
