The antimatter counterpart of a light atomic nucleus can travel a long distance in the Milky Way without being absorbed, shows the international ALICE collaboration in an article published today in Na...
Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
At the Quark Matter conference today and at the recent Rencontres de Moriond conference, the LHCb collaboration presented an analysis of particle collisions at the Large Hadron Collider (LHC) that may...
CP asymmetry is the only non-trivial difference between matter and antimatter found so far. Its discovery in neutral kaon decays in 1964 came as a big surprise to the physics community, but today it i...
ASACUSA sees surprising behaviour of hybrid matter–antimatter atoms in superfluid helium（图）

A hybrid matter--–antimatter helium atom containing an antiproton, the proton’s antimatter equivalent, in place of an electron has an unexpected response to laser light when immersed in superfluid hel...
In a paper published today in the journal Nature, the BASE collaboration at CERN reports the most precise comparison yet between protons and antiprotons, the antimatter counterparts of protons.
Picture two children playing on swings in a playground. One is a daredevil, launching themselves high off the ground in big arcs. The other daydreams, swinging gently.
From antimatter to heavy isotopes, data-taking in physics facilities is resuming at CERN（图）

As the two-year-long shutdown of CERN’s accelerators comes to an end, some of the Laboratory’s many experiments are not waiting for the Large Hadron Collider (LHC) to wake up before starting to take d...
Inverted,but not perfectly:First trace of differences between matter and “ordinary” antimatter

In data collected during the first phase of operation of the Large Hadron Collider the LHCb collaboration team has discovered an interesting asymmetry. The most recent analysis of decays of the beauty...
Physicists closer to understanding balance of matter, antimatter in Universe（图）
Universe Physicists

Physicists in Syracuse University’s College of Arts and Sciences have made important discoveries regarding Bs meson particles—something that may explain why the Universe contains more matter than anti...
Do we live in the universe successively dominated by matter and antimatter?
matter and antimatter universe
2011/8/30
We wonder if a cyclic universe may be dominated alternatively by matter and antimatter. Such a scenario demands a mechanism for transformation of matter to antimatter (or antimatter to matter) during ...
Can the matter-antimatter asymmetry be easier to understand within the "spin-charge-family-theory", predicting twice four families and two times $SU(2)$ vector gauge and scalar fields?
the matter-antimatter asymmetry spin-charge-family-theory
2010/12/27
This contribution is an attempt to try to understand the matter-antimatter asymmetry in the universe within the {\it spin-charge-family-theory} if assuming that transitions in non equilibrium processe...

New particle dark matter missing antimatter
2010/11/30
Physicists in the US and Canada have proposed a new particle that could solve two important mysteries of modern physics: what is dark matter and why is there much more matter than antimatter in the un...

2010/9/21
Neutrinos, elementary particles generated by nuclear reactions in the sun, suffer from an identity crisis as they cross the universe, morphing between three different “flavors.” Their antimatter count...

2010/3/26
Physicists working in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven Laboratory in the US have detected antimatter nuclei containing strange quarks for the firs...
