LHC team observes first instance of D-mesons oscillating between matter and antimatter
(Phys.org) —Researchers working at the Large Hadron Collider (LHC) have observed for the first time evidence of D-mesons oscillating between matter and antimatter. They describe their work, observations and the degree of ...
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. ...

How the Earth stops high-energy neutrinos in their tracks
Neutrinos are abundant subatomic particles that are famous for passing through anything and everything, only very rarely interacting with matter. About 100 trillion neutrinos pass through your body every second. Now, scientists ...

BaBar experiment data hint at cracks in the Standard Model
(Phys.org) -- Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, ...
