Particle physicists are delving deep into the Standard Model of particle physics to better understand quark mixing, which is not accurately predicted by the model. The quarks that form the nuclei of ...

Most top quarks are produced in top–antitop pairs by the strong force. The production rate for this process is substantial (it has a cross-section of about 7 picobarns) and the presence of two ...

That’s because, as far as we know, electrons are fundamental particles. In other words, they have no smaller components. That ...

A team of international researchers has developed a framework that promises to reveal the many secrets of quark mixing.

Nuclear theorists at Brookhaven National Laboratory and Argonne National Laboratory have successfully employed a new ...

This book describes the development of our understanding of the strong interactions in particle physics, through its competing ideas and personalities, its false starts, blind alleys, and moments of ...

The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally ...

Nuclear scientists have developed a new theoretical approach that offers a more precise calculation of the 3D motion of ...

Display of a lead–lead collision at 5.02 TeV per nucleon pair that resulted in a candidate pair of top quarks that decay into other particles. The event contains four particle jets (yellow cones ...

At the Large Hadron Collider in Geneva, the world's largest particle accelerator, an experiment called ATLAS has just found ...
