When trying to identify the nature of dark matter, sometimes it’s the things it doesn’t do that tell us the most, like turning the center of the Earth liquid. A new study has shown that if some models ...

Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter ...

Neutrinos are very common fundamental particles included in the Standard Model of particle physics. Measuring their ...

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place. Obviously that didn't happen. Experiments at the Large Hadron Collider (LHC) may ...

“The mass and the antiparticle nature of neutrinos can be studied by measuring the radioactive beta and double-beta decays of ...

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

Understanding why we live in a matter-dominated universe demands that scientists recreate the quark-gluon plasma that existed one millionth of a second after the Big Bang. A Large Ion Collider ...

A Hiroshima University team has designed a feasible way to detect the Unruh effect, where acceleration turns quantum vacuum ...

In the alphabet-soup world of subatomic physics, only one letter was missing. The equations of quantum theory had indicated the existence of 17 pairs of basic “building blocks”—particles and ...

An experiment more than 10 years in the making has delivered its first glimpse of the hurricane of particles whirring inside subatomic particles called neutrons, laying the groundwork to solve a ...

An artistic representation of antihyperhydrogen-4 — an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle — created in a collision of two gold nuclei (left).
