...The experiments, smashing protons into each other, produced a few more subatomic particles known as pions and kaons than the team was expecting.

"The level is somewhat higher than the most popular models had predicted, and it looks like it is going to increase with energy a little bit more steeply than we expected," said Roland Gunter, a CMS collaboration scientist from the Massachusetts Institute of Technology in the US.

"I think it's not going to be a problem, but it is one of the many things that we need to know as we move toward searches for the most rare particles and new physics," he told BBC News.
...
"We'll know much more about that in two or three months when we look at the next higher energy of 7 TeV (trillion electron volts)."
