How many kinds of elementary particles should I say there are? In experiments at the Large Hadron Collider, physicists smash ...

An unexpected behavior in a particle decay seems to disagree with the predictions of the Standard Model, despite its high ...

Researchers at the Max Planck Institute for Quantum Optics (MPQ), Garching, in collaboration with Prof. Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), ...

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...

Learn about new research that is undermining the Standard Model, a framework that has guided particle physics for decades. For the last half century, particle physics has been dominated by a framework ...

Red lines show the disintegration of a B-sub-s into two muons in the CMS camera at the Large Hadron Collider. Yello, green and blue are used to denote particles other than muons. Purdue University ...

Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and ...

Mark Thomson has taken the reins at CERN just as particle physics confronts some of its deepest unknowns – and faces hard ...

Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...

A Practical Step-by-Step Guide, by Marco Fabbrichesi, offers an intermediate-level presentation of the Standard Model.
