Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles ...

A rather unassuming particle is playing an important role in the hunt for subatomic oddities. Similar to protons and neutrons, mesons are composed of quarks bound together by the strong nuclear force.

An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider ...

Scientists observe CP violation in baryons, a key clue in understanding why matter dominates the universe over antimatter.

During those very early moments of the universe, things were extraordinarily hot, and quark-gluon plasma behaves in strange ...

So physicists have been on the hunt for any sign of difference between matter and antimatter, known in the field as a ...

The new measurement from LHCb has found differences between baryons and antibaryons, which are made of three quarks and three ...

In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up ...

Since the 1960s, we have known that these particles violate the so-called charge-parity (CP) symmetry. The antimatter counterpart behaves in a different way. It had long been suspected, with ...
