A Breakthrough in Measuring the Elusive Weak Nuclear Force A few weeks ago, a groundbreaking experiment successfully measured ...

The internal pressure within the particles that make up each atom in the Universe might exceed the pressure found in the ...

Scientists have observed particles forming from the vacuum, revealing how matter may emerge from seemingly empty space.

Protons were shown to consist of quarks in 1968, but the question of whether quarks are made of even smaller particles is as yet unanswered. (Image: A. Iqbal/ CMS) At this scale, no evidence of ...

According to our current understanding of the universe, quarks are fundamental, point-like particles: basic building blocks that are not made up of smaller particles. A recent paper from the CMS ...

Seemingly empty vacuums are actually teeming with perturbations known as virtual particles that are nearly impossible to detect. Virtual particles vanish quickly, but by smashing protons at ...

In 2021, Fermilab carried out seaquest experiment to find the number ratio of anti-up quark to anti-down quark in proton. Protons contain three valence quarks and a large number of sea quarks. The ...

After years of failed searches, CERN has finally caught a needle in a subatomic haystack: a heavy relative of the proton called Ξcc⁺. Ξ (or Xi) is a Greek letter pronounced like the word “Zye” (rhymes ...

Physicists from the LHCb experiment at CERN’s Large Hadron Collider (LHC) have discovered a new kind of heavy proton-like particle. Known as Ξcc⁺, this particle contains two charm quarks and one down ...
