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.
