A boiling sea of quarks and gluons, including virtual ones—this is how we can imagine the main phase of high-energy proton ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

At the world’s most powerful colliders, physicists are finally catching sight of particles that almost never leave a trace, a ...

An invisible force has long eluded detection within the halls of the world’s most famous particle accelerator—until now.

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Seeing the proton beam Top row: relative dose distribution in a water phantom for 200, 207 and 215 MeV proton beams at 32 nA, as measured by radiochromic film. Middle row: MR images showing the ...

Proton running for 2010 in the LHC at CERN came to a successful conclusion on November 4. Since the end of March, when the first collisions occurred at a total energy of 7 TeV, the machine and ...

Physics is insane, and doesn’t always follow the laws we’ve formulated over the last several thousands of years of accrued observation and analysis. Case in point: a new study published today in ...

How big is a proton? This doesn’t sound like a very complicated question, but it’s one that turned out to have the potential to wreck a lot of modern physics. That’s because different methods of ...
