What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That number discrepancy lies at the heart of a new conundrum of kaons: ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

A research team led by Rice University physicist Frank Geurts has successfully measured the temperature of quark-gluon plasma (QGP) at various stages of its evolution, providing critical insights into ...

The CMS Collaboration investigated in detail events in which a top quark and an anti‑top quark are produced together in high‑energy proton–proton collisions at √s = 13 TeV, using the full 138 fb⁻¹ ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that ...

Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...

Scientists have for the first time observed quantum entanglement — a state in which particles intermingle, losing their individuality so they can no longer be described separately — between quarks.

Heavy-ion physics is a dynamic field that investigates the behaviour of matter under extreme conditions by colliding nuclei at relativistic speeds. Such collisions create a short-lived, ...

The ALICE experiment of the Large Hadron Collider has, for the first time, directly measured a phenomenon known as the "deadcone," which has allowed physicists to directly measure the mass of a ...
