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 ...

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 ...

The Isotope Separator On-Line facility (ISOLDE) directs a proton beam from the Proton Synchrotron Booster (PSB) onto ...

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 ...

For almost a decade, physicists have been baffled by the so-called proton radium puzzle: using different methods of measurement, they obtained two numbers that are slightly yet significantly different ...

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 ...

WASHINGTON, D.C., July 20, 2009 -- Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine (AAPM) ...

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 ...

An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. The experiment, called G-Zero, was ...

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 ...
