Quick update on the Large Hadron Collider. Below is a recent press release, but the bottom line is that the machine is up and running again, and all is working well.
Two beams of protons are firing around the 27 km long tunnel, engaging in billions of collisions. Their energy has reached the unprecedented level of what's called "13 TeV," which is roughly double that of earlier run which resulted, for example, in the discovery of the Higgs particle.
So far, the focus has been mostly on using the data to test all of the experimental systems by reproducing known physics--everything that fits under the rubric of the "Standard Model of Particle Physics" (electrons, quarks, neutrinos, etc. all interacting by the strong, weak and electromagnetic interactions). The goal is to shortly go beyond this and, fingers crossed, find new physics that stands outside of the Standard Model.
It is exciting to be navigating in unchartered waters...
