What's the sound of 2 Hadrons colliding?

[Bells]

From Wikipedia

On March 30 2010, the first collisions took place between two 3.5 TeV beams. This set a world record for the highest energy man-made particle collisions.

The first p-p collisions at energies higher than Fermilab's Tevatron p-pbar collisions have been published on arXiv, yielding greater-than-predicted charged hadron production. The CMS paper reports that the increase in the production rate of charged hadrons when the center-of-mass energy goes from 0.9 TeV to 2.36 TeV exceeds the predictions of the theoretical models used in the analysis, with the excess ranging from 10% to 14%, depending upon which model is used. The charged hadrons were primarily mesons (kaons and pions).

So, it finally worked and it produced 14% more Hadrons causes 25% more Hard'ons on scientistis! *Ba~dum-tish*
