The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Scientists have made an unprecedented close examination of the electron, providing fascinating new insights into the nature of particles, energy and forces at infinitesimally small scales. A ...

What is our Universe made out of? At a fundamental level, to the best of our knowledge, the answer is simple: particles and fields. The type of matter that makes up humans, Earth, and all the stars, ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Predicting the properties of subatomic particles before their experimental discovery has been a big challenge for physicists. Predicting the properties of subatomic particles before their experimental ...

Electrons are extremely round, and some physicists are not pleased about it. A new experiment captured the most detailed view of electrons to date, using lasers to reveal evidence of particles ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...
