Sometimes, everyday words are co-opted by scientists and used as technical terms. One of these is the word “berry”. Talking to a botanist friend of mine, I learned that tomatoes are berries, but strawberries are not — the scientific meaning of a...

In the early hours of 14 February 2013, the first period of running for the Large Hadron Collider came to an end. After three very fruitful years of collisions at the LHC, the blank screens of LHC Page 1 seem very odd. “End of Run 1. No beam for a...

The LHC has just delivered the first pPb (proton-lead) collisions with stable beams of 2013 and CMS is happily running with all sub-detectors on. We are also having common triggers with TOTEM and everything is behaving very well. Thanks a lot to all...

The new year brings a new type of collision at the LHC: the accelerator will smash protons and lead nuclei together, allowing CMS and the other LHC experiments to study the cold nuclear matter we expect these collisions to produce. Although we...

In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions “melt” as a consequence of interacting with the hot nuclear matter created in these heavy-ion interactions. CMS has since updated and extended this...

In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns. A recent CMS observation...

Collaborations of high-energy physicists often number in the thousands, and this presents some unique challenges. “CMS is a big collaboration, with 3,000 people from diverse backgrounds, speaking different languages,” says Sudhir Malik, co-convener...
