Long-sought decay of Higgs boson observed

Six years after its discovery, the Higgs boson has at last been observed decaying to fundamental particles known as bottom quarks. The finding, presented today at CERN by the ATLAS and CMS collaborations at the Large Hadron ...

'New physics' charmingly escapes us

In the world of elementary particles, traces of a potential "new physics" may be concealed in processes related to the decay of baryons. Analysis of data from the LHCb experiment at the Large Hadron Collider performed by ...

Secrets of the Big Bang and dark matter

At the Japanese Research Center for Particle Physics KEK, the new particle accelerator experiment Belle II started operation after eight years of construction. Scientists from all over the world eagerly waited for news on ...

When fluid flows almost as fast as light—with quantum rotation

Quark-gluon plasma is formed as a result of high-energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds (10-24 seconds), this most perfect of all known fluids undergoes rapid hydrodynamic expansion ...

The chances of detecting clumps in atomic nuclei are growing

What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case ...

Higgs boson, top quarks linked in milestone collider discovery

An observation made by an experiment at the Large Hadron Collider involving Florida Institute of Technology physicists Francisco Yumiceva, Marcus Hohlmann and Marc Baarmand has for the first time connected the two heaviest ...

Neutron stars cast light on quark matter

Quark matter – an extremely dense phase of matter made up of subatomic particles called quarks – may exist at the heart of neutron stars. It can also be created for brief moments in particle colliders on Earth, such as ...
