Precise Measurement of Pions Confirms Understanding of Fundamental Symmetry

Scientific rules about “chiral symmetry” predict the existence of subatomic particles called pions. The lifetime of a neutrally charged pion is tied to breaking of chiral symmetry. Until recently, measurements of this lifetime have been much less precise than calculations from theory. Physicists have now measured a pion’s lifetime more precisely than ever before.

Signs of “Turbulence” in Collisions that Melt Gold Ions

A new analysis of collisions of gold ions shows signs of a “critical point,” a change in the way one form of matter changes into another.

This helps scientists understand how particles interact and what holds them together.

New IceCube detection proves 60-year-old theory

Normally, electron antineutrino would zip right through the Earth at the speed of light as if it weren’t even there. But this particle just so happened to smash into an electron deep inside the South Pole’s glacial ice, and was caught by the IceCube Neutrino Observatory. This enabled IceCube to make the first ever detection of a Glashow resonance event, a phenomenon predicted 60 years ago by Nobel laureate physicist Sheldon Glashow.

The result was published March 10 in Nature.
