CP violation or new physics?
(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. ...

Explainer: What is antimatter?
Antimatter was one of the most exciting physics discoveries of the 20th century. Picked up by fiction writers such as Dan Brown, many people think of it as an "out there" theoretical idea – unaware that it is actually being ...

Physicists propose mechanism that explains the origins of both dark matter and 'normal' matter
(PhysOrg.com) -- Through precise cosmological measurements, scientists know that about 4.6% of the energy of the Universe is made of baryonic matter (normal atoms), about 23% is made of dark matter, and the remaining 72% ...
Coldest Antimatter Ever Produced

Are there antimatter galaxies?
One of the biggest mysteries in astronomy is the question, where did all the antimatter go? Shortly after the Big Bang, there were almost equal amounts of matter and antimatter. I say almost, because there was a tiny bit ...

Physicists find ways to increase antihydrogen production
(Phys.org)—There are many experiments that physicists would like to perform on antimatter, from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these ...
Electron is surprisingly round, say scientists following 10 year study
(PhysOrg.com) -- Scientists at Imperial College London have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere, in a study published in the journal Nature ...

Time's quantum arrow has a preferred direction: BaBar experiment confirms time asymmetry
(Phys.org)—Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the ...
