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 ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

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 ...

A giant detector buried deep within the Antarctic ice at the South Pole has obtained the first evidence of eerie particles called neutrinos coming from the innards of our own home galaxy, the Milky ...

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 ...

Here’s what you’ll learn when you read this story: When analyzing early universe data, the Standard Model of Cosmology suggests that the universe should be more “clumpy” that what we observe. A new ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

In one second, an estimated 100 billion neutrinos pass through every square centimeter of your hand. These subatomic particles traveling to Earth are a byproduct of nuclear reactions that occur in the ...

China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

TRONDHEIM, Norway — Particles racing through space at nearly the speed of light pack energy millions of times greater than anything we can create on Earth. For decades, these cosmic bullets have ...
