The plot thickens for a hypothetical X17 particle
Fresh evidence of an unknown particle that could carry a fifth force of nature gives the NA64 collaboration at CERN a new incentive to continue searches.

For the LHCb detector at the Large Hadron Collider, the ongoing second long shutdown (LS2) of CERN's accelerator complex will be a period of metamorphosis. After two successful data-collection runs, the detector is being ...

Finding a new particle is always a nice surprise, but measuring its characteristics is another story and just as important. Less than a year after announcing the discovery of the particle going by the snappy name of Ξcc++ (Xicc++), ...

From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists ...

Our world consists mainly of particles built up of three quarks bound by gluons. The process of the sticking together of quarks, called hadronisation, is still poorly understood. Physicists from the Institute of Nuclear Physics ...

In the first moments after the Big Bang, the universe expanded many billions of times faster than today. Such rapid expansion is likely due to a primordial force field acting with a new particle, the inflaton. From the latest ...
