In recent investigations with the photographic method 1,2, it has been shown that slow charged particles of small mass, present as a component of the cosmic radiation at high altitudes, can enter ...

As in the previous communications1, we refer to any particle with a mass intermediate between that of a proton and an electron as a meson. It may be emphasized that, in using this term, we do not ...

Particle physicists at CERN have measured charge-parity (CP) violation in the D 0 meson for the first time. Announcing the finding today during the annual Rencontres de Moriond conference held in La ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they ...

Carnegie Mellon University's Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and neutrons. For the first time, researchers have provided measurements ...

“Where has all the antimatter in the universe gone?” is one of the great unanswered questions in cosmology. Now, an unexpected difference in the behaviour of two types of exotic particle seen at an ...

Researchers associated with the Continuous Electron Beam Accelerator Facility (CEBAF) at the Department of Energy’s Thomas Jefferson National Accelerator Facility have taken the first step toward ...

Karthik Suresh’s doctoral dissertation on meson decay in the ongoing GlueX Collaboration at Jefferson Lab has just earned the prestigious 2023 Jefferson Science Associates (JSA) Thesis Prize. NEWPORT ...

Scientists at the Department of Energy’s Fermi National Accelerator Laboratory will announce on Friday, June 18 the observation of an unexpected new member of a family of subatomic particles called ...

Matter and antimatter particles can behave differently, but where these differences show up (and where they don’t) is still a puzzle. About 90% of people are right-handed. This human preference for ...

Russian nuclear physicists announced a discovery last week, the first they have made since the war (or been allowed to talk about). Physicists P. I. Lukirsky and N. A. Perfilov told the Academy of ...
