In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei.

While radiation treatments designed to kill cancer cells have come a long way, scientists and doctors are always exploring ...

A proton has two up quarks and one down quark, and they're held together by gluons: massless, color-charged particles which mutually bind the three quarks together.

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 ...

The study demonstrated that – in addition to a single proton field offering a higher therapeutic index than a single photon field – a low number of proton fields can outperform VMAT, the most ...

Physics is somewhat less broken, but still not quite right Measurements of the proton’s charge radius still disagree, but by less.

Our annual proton-therapy physics workshop is a logical extension of PPRIG’s remit, bringing the UK proton-physics community together with leading researchers from overseas.” It’s good to talk: ...

Studying how quarks inside protons move in response to electric fields shows that protons seem to stretch more than theory says they should.

The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top ...

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

Physics: Proton radius smaller than believed, European scientists say By Thomas H. Maugh II, Los Angeles Times July 7, 2010 12 AM PT ...

Physics Physicists surprised to discover the proton contains a charm quark The textbook description of a proton says it contains three smaller particles - two up quarks and a down quark - but a ...
