LHCb experiment observes new matter-antimatter difference

(Phys.org) —The LHCb collaboration at CERN today submitted a paper to Physical Review Letters on the first observation of matter-antimatter asymmetry in the decays of the particle known as the B0s. It is only the fourth ...

A 5-sigma standard model anomaly is possible

One of the best chances for proving beyond-the-standard-model physics relies on something called the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The standard model insists that the CKM matrix, which describes the mixing of quarks, ...

More JWST observations are finding fewer early massive galaxies

There's a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we've never had before, the data threatens to overturn all we've assumed about some long-established theory, ...

No evidence of the double nature of neutrinos

After two years of searching for a special radioactive decay that would provide an indication of new physics beyond the standard model, an experiment deep under ground near Carlsbad has so far found no evidence of its existence. ...
