Observations challenge cosmological theories

Recent observations have created a puzzle for astrophysicists: Since the Big Bang, fewer galaxy clusters have formed over time than were actually expected. Physicists from the university of Bonn have now confirmed this phenomenon. ...

ATLAS Experiment releases new study of ultra-rare B-meson decay

The study of hadrons—particles that combine quarks to form mesons or baryons—is a vital part of the physics programme by researchers of the ATLAS Experiment at CERN. Their analysis has not only perfected the understanding ...

The hunt for leptoquarks is on

Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make up protons and neutrons). ...

Higgs boson observed decaying to b quarks

On 9 July, at the 2018 International Conference on High Energy Physics (ICHEP) in Seoul (South Korea), the ATLAS experiment reported a preliminary result establishing the observation of the Higgs boson decaying into pairs ...

Long live the doubly charmed particle

Finding a new particle is always a nice surprise, but measuring its characteristics is another story and just as important. Less than a year after announcing the discovery of the particle going by the snappy name of Ξcc++ (Xicc++), ...

The apparent inner calm of quantum materials

Researchers from the University of Geneva (UNIGE) and multi-institutional collaborators have been studying BACOVO—a one-dimensional quantum material. They report that the material exhibits a novel topological phase transition ...

Water purification breakthrough uses sunlight and 'hydrogels'

According to the United Nations, 30,000 people die each week from the consumption and use of unsanitary water. Although the vast majority of these fatalities occur in developing nations, the U.S. is no stranger to unanticipated ...
