LHC Restarts after Two Years of Shutdown

The ongoing European Physical Society High Energy Physics conference is the first big opportunity for researchers at the Large Hadron Collider (LHC) to show what they have extracted from the new data since the Large Hadron Collider restarted on 3 June.

LHC scientists hope that in the collider's second run, they would break new ground with the overhauled collider. In the collider's first run from 2010 to 2013, physicists discovered the Higgs boson, a breakthrough that closed a long-standing gap in the theory about how subatomic particles behave.

Rolf Heuer, director general of the European Organization for Nuclear Research, or CERN, in an interview said they hope that they would be able to find light in the dark universe.

At a European Physical Society High Energy Physics conference in Vienna on Monday, CERN will be briefing nearly 700 scientists about the collider's second run, which began earlier this month and extends until 2018.

CERN will also be presenting fresh data about the Higgs, a fundamental particle that gives mass to other particles. "We've done more precise measurements about the Higgs and have more information about its properties", Dr. Heuer said.

As per experts, the collider smashes the protons together at speed almost similar to the speed of light. These collisions are mini-versions of the primordial blast known as the big bang that brought the universe into being 13.8 billion years ago, they said.

Since collider's shut down in February 2013, several hundreds of engineers and technicians have been upgrading the machine to prepare for particle collisions at far higher energy levels.
