Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

CERN’s Large Hadron Collider (LHC) is designed to probe the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s still early days, the discovery ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

The quantum world is notoriously difficult to comprehend. As Niels Bohr famously stated, “Anyone who is not shocked by quantum theory has not understood it.” One of the things we pride ourselves on ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find. When you purchase through links on our site, we may earn ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

The Standard Model of Particle Physics is the collection of discoveries and theories that describe the smallest units of matter and the interactions between energy and matter. According to this model, ...

Dominika Vasilkova receives funding from the Leverhulme Trust. Ce Zhang receives funding from the Leverhulme Trust. Elia Bottalico receives funding from the Leverhulme Trust. Saskia Charity receives ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

Holger Müller is in the Department of Physics, University of California, Berkeley, Berkeley, California 94720, USA. However, the recoil energy is tiny and therefore hard to measure. Laser-based ...

Roger Jones receives funding from STFC. I am a member of the ATLAS Collaboration As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is ...
