After parsing that article to get the paper link, that is insane. I am not in the field, but find it curious that each every person of that list of authors had direct significant contribution. Not my field though so just seems odd.
> The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008, in collaboration with over 10,000 scientists, and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
They give credit to everyone who built the instrument, wrote the software pipelines to analyze the data, etc. That's thousands of people. That's how large experimental projects work.
