Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

Scientists have now mapped the forces acting inside a proton, showing in unprecedented detail how quarks—the tiny particles within—respond when hit by high-energy photons. The international team ...

Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to ...

The CMS collaboration at CERN have searched for evidence of long-lived particles beyond the Standard Model in proton-proton collision events Despite the huge success of the Standard Model of particle ...
