AEgIS collaboration achieves laser cooling of positronium at CERN’s antimatter factory

AEgIS is one of several experiments at CERN’s Antimatter Factory producing and studying antihydrogen atoms with the goal of testing with high precision whether antimatter and matter fall to Earth in the same way. In a paper published today in Physical Review Letters, the AEgIS collaboration reports an experimental feat that will not only help … Read more

Mass–energy equivalence

Mass–energy equivalence is a profound and revolutionary concept that lies at the heart of modern physics. The equation E=mc², formulated by Albert Einstein in 1905, encapsulates this principle and signifies the intrinsic relationship between mass (m) and energy (E). This equation has far-reaching implications, reshaping our understanding of the universe and paving the way for … Read more

Entanglement enhances search for new physics

Physicists, in their quest for new particles and forces in nature, actively seek behaviors within atoms and molecules that defy the established Standard Model of particle physics. Any deviations from this model could signify the presence of what physicists affectionately term “new physics.” Caltech’s Assistant Professor of Physics, Nick Hutzler, and his research group are … Read more

PROSPECT collaboration reports most precise measurement of antineutrino energy spectrum

The neutrino, a remarkably elusive and poorly understood subatomic particle, rarely interacts with matter, posing a challenge for precise studies. Nuclear reactors, the most potent sources of neutrinos on Earth, play a vital role in exploring these mysterious particles. The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) was specifically designed for in-depth examinations of electron … Read more

New experiment confirms that gravity pulls antimatter down

In a recent experiment conducted by physicists at the European Center for Nuclear Research (CERN) in Geneva, Switzerland, the hope that antimatter might defy gravity and levitate has been definitively dispelled. This experiment focused on antihydrogen, composed of an anti-proton and an antielectron (positron), and its response to gravity. The results, published in the September … Read more

Scientists create alice rings in nature, proving decades-old theory

The realm of quantum physics offers intriguing avenues for exploration, and one particular rabbit hole presents a novel perspective into a world where particles exhibit peculiar behaviors, much like the world behind the looking glass. Named the “Alice ring” in homage to Lewis Carroll’s iconic tales of Alice’s Adventures in Wonderland, this object’s emergence validates … Read more

JILA sets new record for precision measurement of electron electric dipole moment

In the early moments of the universe, matter and antimatter particles were formed, including protons, neutrons, electrons, and their antimatter counterparts. As the universe expanded and cooled, most of these particles annihilated each other, leaving behind only photons or light. However, if the universe were perfectly symmetrical with equal amounts of matter and antimatter, there … Read more

New hadron measurements improve estimations of neutrino beam content

The mystery of why there is more matter than antimatter in the universe has puzzled scientists for years. One possible explanation lies in the behavior of neutrinos, particles that lack electrical charge and can change their identity as they travel through space. Researchers are conducting experiments, such as the NOvA experiment in the US and … Read more
