I am looking for the famous CMS and ATLAS papers which announced the discovery of a new boson particle...
Could someone help me by posting the link here?
The papers you search for are easier to find through inspire. Here is the link for the CMS papers on inspire sorted on number of citations:

As you can imagine, the discovery announcement is the first. I am sure you can figure out how to find the ATLAS paper in the same fashion.
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.
