Even though the Standard Model is now an orphan theory, having outlasted its primary architects, its reign as the most successful theory in the history of science continues, and so shall the ...

A key theory of particle physics, the Standard Model has withstood test after test. But there are holes in the theory, particularly when it comes to gravity.

Precise measurements of already discovered particles are shaking up physics, according to a scientist working at the Large Hadron Collider.

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

Recently, a series of precise measurements of already known, bog-standard particles and processes have threatened to shake up physics.

The Standard Model is the guiding light of particle physics. At its barest essence, the theory describes the 17 fundamental particles (six quarks, six leptons, and five bosons) that make up normal ...

After refinement in the theory and high-precision experiments, scientists have finally announced that the standard model of particle physics continues to be correct.

A deviation from the Standard Model prediction could therefore mean that there are more particles than those that are currently known—or that there is some other new physics, such as additional ...

Ultimately, breaking the CKM matrix unitarity -- and finding physics beyond the standard model -- would demand a stronger discrepancy between theory and experiment.

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the ...

Recently, a series of precise measurements of already known, bog-standard particles and processes have threatened to shake up physics.

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 ...
