W bosons are subatomic particles responsible for a fundamental force at the centre of atoms. They exist for only a fraction of a second before they decay into other particles. W bosons govern what ...

The subatomic particle that has a negative charge is the electron. Out of the three subatomic particles that compose an atom, the electron has the smallest mass.

The new particles are versions of what is known as the charged Xi baryon – a short-lived cousin of the proton, which is an essential component of every atom in the universe.

Muons are subatomic particles that are similar to electrons but around 200 times heavier. At high energy, they can easily travel through hundreds of yards of solid rock.

This effect has been predicted by the Standard Model of physics and observed experimentally in subatomic particles called mesons more than 60 years ago, but never previously observed in baryons.

Blusk and Charles jointly analyzed the data that led to this discovery. The data was generated by the LHCb experiment at the Large Hadron Collider near the border of France and Switzerland. LHCb is an ...

A group of teenaged students from Cambridge, Ont., is hunting for new subatomic particles at the home of the world's largest atom smasher this week. They hope to turn up what particle physics PhDs ...
