Welcome back, LHC

Recently I have come across news reports which say that the Large Hadron Collider (LHC) has restarted after two years of intense maintenance and consolidation, and several months of preparation. That means the most powerful particle accelerator in the world is back in operation with protons circling the machine's 27 km tunnel for the first time since 2013.

In fact, now the beams will be set up in such a way that they will produce more collisions by bunching protons closer together and it would be possible because of improved magnet protection system. The technical stop of the LHC should be considered a Herculean task because at least 10,000 electrical interconnections between the magnets were consolidated. However, it is said that physicists are frustrated by the existing Standard Model of particle physics. In order to explain several baffling properties of the universe, things beyond the Standard Model have been proposed - but never directly detected. We hope scientists will discover new physics beyond the Standard Model.
