Scientists in Germany said Wednesday they had made the most precise measurement yet of the mass of the electron, one of the building blocks of matter.
New measurements of the electron have confirmed, to the smallest precision attainable, that it has a perfect roundness -- this is bad news for theories of physics beyond the standard model. Continue reading →
While looking for a strange state of matter in two particle accelerators, it has been announced that another, totally unexpected, particle has been discovered. Continue reading →
The Large Hadron Collider (LHC) has recreated the world's tiniest droplets of a primordial state of matter that last existed moments after the Big Bang, some 13.82 billion years ago. Continue reading →
Forget the Higgs boson's delusions of grandeur, the exchange particle that gives stuff mass appears to be something of a disappointment. ->
A high-energy experiment at the SLAC National Accelerator Laboratory is turning up results that challenge the Standard Model of physics.
When a star dies, depending on its mass, it will form a white dwarf, neutron star or a black hole. Or will it? Perhaps there's an intermediate "electroweak" phase that may save the remnant from black hole doom.
After the early announcement on Friday that CERN had successfully circulated the first protons around the 17 mile-long ring of the Large Hadron Collider (LHC), really early news of the first ever particle collisions inside the LHC has been announced. According to several sources, these low-energy c...
