The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

In a discovery that has physicists relearning how to count, three teams around the globe report that they have identified a subatomic particle consisting of five quarks -- a number never before seen ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

Quarks are elemental particles, with no sub-structure. Understanding them is crucial to learning how physics works on the smallest levels. By studying collisions of incredibly small particles made up ...

The grand explanation physicists use to describe how the universe works may have some major new flaws to patch after a fundamental particle was found to have more mass than scientists thought. “It’s ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

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 ...

Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics. Fundamental particles are objects that are so small, they have no deeper ...

College of Arts and Sciences (A&S) physicists at Syracuse University have launched a new tracking device to research the fundamental forces and particles in the universe. The device, known as the ...

Before he was a UC Davis professor studying the subatomic particles underlying the universe, Manuel Calderón de la Barca Sánchez was an engineering physics student at the Monterrey Institute of ...
