New subatomic particle discovery may challenge the Standard Model and explain why matter dominates over antimatter in the ...

The Standard Model explains three fundamental forces—electromagnetism, the weak force, and the strong force—but gravity ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. Image: Mikko Partanen and Jukka Tulkki / ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Neutrinos are elementary particles in the Standard Model of particle physics and are very common in nature. They are produced, for example, by nuclear reactions in the sun. Every second, trillions ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...
