The Large Hadron Collider: Countdown

On September 10, the world's biggest science experiment is set to come online. Here's how the LHC will search for the Higgs boson, dark matter and supersymmetry

The Large Hadron Collider Goes to Work

Nobel Prize-winning physicist Frank Wilczek and Scientific American editor George Musser talk about the Large Hadron Collider, the most powerful particle accelerator ever built, which went online this week. Plus, we'll test your knowledge about some recent science in the news. Web sites mentioned in this episode include;;

Large Hadron Collider (LHC) is live--And so are we

The particle-smashing Large Hadron Collider(LHC) is up and running, and we're still here.

"We've got a beam on the LHC," project leader Lyn Evans told his colleagues to applause after the machine finished coaxing a beam of protons around the 17-mile (27-kilometer) tunnel at 10:28 a.m.

The Mysteries of Mass

Physicists are hunting for an elusive particle that would reveal the presence of a new kind of field that permeates all of reality. Finding that Higgs field will give us a more complete understanding about how the universe works

Fermilab says: "Hey wait, we're in the Higgs hunt, too!"

It looks like the Large Hadron Collider (LHC) may have some competition in its search for the much-anticipated Higgs boson, the source of mass.

Yesterday CERN, the European particle physics lab, announced that on September 10 it would begin shooting protons around the full 27 kilometers (17 miles) of the circular LHC—the most powerful particle accelerator ever built—building up to collisions with a second, opposing beam in subsequent months.

Building the Next Generation Collider

To further investigate the intricacies of high-energy particle physics, researchers must construct a more powerful electron-positron collider

Large Hadron Collider countdown going strong

CERN loves the smell of protons in the morning. Last Friday the European particle physics lab began testing the system for injecting a proton beam into the Large Hadron Collider (LHC), which if you haven't heard by now is a giant particle accelerator 27 kilometers (17 miles) in circumference.

Uncovering Supersymmetry

A strange,elusive phenomenon called supersymmetry was conceived for elementary particle physics--but has come to light in nuclei of platinum and gold

A Unified Physics by 2050?

Experiments at CERN and elsewhere should let us complete the Standard Model of particle physics, but a unified theory of all forces will probably require radically new ideas.
