Neutron stars may hold an answer to neutron puzzle on Earth

According to University of Illinois physicist Douglas H. Beck, "Neutrons play some unusual roles in our world. Free neutrons decay in about 900 s but, bound in nuclei, they are stable and make up somewhat more than half the ...

Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, ...

Light may unlock a new quantum dance for electrons in graphene

A team of researchers has devised a simple way to tune a hallmark quantum effect in graphene—the material formed from a single layer of carbon atoms—by bathing it in light. Their theoretical work, which was published ...

New particle flow algorithm improves ATLAS experiment precision

Proton collisions in the Large Hadron Collider often result in the production of "jets" of particles. These jets are a key element in the measurement of many processes, such as the decays of Higgs bosons or other exotic particles. ...

LHCb unveils new particles

On 28 June, the LHCb collaboration reported the observation of three new "exotic" particles and the confirmation of the existence of a fourth one in data from the Large Hadron Collider (LHC). These particles seem to be formed ...
