Examining the delicate balance of lepton flavors

In a talk at the ongoing Rencontres de Moriond conference, the ATLAS collaboration presented the result of its latest test of a key principle of the Standard Model of particle physics known as lepton flavor universality. ...

Scientists investigate how cerium is produced in the universe

Cerium is a rare Earth metal that has numerous technological applications, for example, in some types of lightbulbs and flat-screen TVs. While the element is rare in Earth's crust, it is slightly more abundant in the universe. ...

FASER measures high-energy neutrino interaction strength

Operating at CERN's Large Hadron Collider (LHC) since 2022, the FASER experiment is designed to search for extremely weakly interacting particles. Such particles are predicted by many theories beyond the Standard Model that ...

New method to measure entropy production on the nanoscale

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. An equation developed by researchers at Chalmers University of Technology in Sweden, and Heinrich Heine University ...
