Collaboration has obtained a high-precision cosmic-ray boron spectrum in the energy range of 10 GeV/n–8 TeV/n, and discovered ...
The charge radius is a statistical measure of how far the electric charge of a particle extends into space. Both groups were ...
Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up.

Exciting the alpha particle: International team validates helium-4 transition calculations - MSNA recent experiment in Germany studied the helium-4 nucleus, also known as an alpha particle. Helium-4 consists of only two protons and two neutrons, making it relatively easy to describe using ...
The Helium in Macy’s Thanksgiving Day Parade Balloons Could Power Some Sweet Science ... The element is used for cooling down particle colliders, cleaning out rocket tanks, and more.
En route to record-breaking X-rays, SLAC’s Cryogenic team built a helium-refrigeration plant that lowers the LCLS-II accelerator to superconducting temperatures.
In a series of high-energy particle collisions, elements like helium are formed in the early universe. Here, D stands for deuterium, an isotope of hydrogen with one proton and one neutron, ...
Helium also cools particle accelerators, quantum computers, and the infrared detectors on the James Webb Space Telescope. As a gas, helium whisks heat away from silicon to prevent damage in ...
Helium is made up of two protons and two neutrons, and hydrogen is just one proton and no neutrons. So the fewer the neutrons available in the early universe, the less helium would be produced.
What is weird though is the fact that it detected antihelium—basically an opposite helium particle. The team expected to get about one detection of antihelium every few decades or so.
