New research could tell us about particle interactions in the early universe and even hint at new physics. Much of the matter in the universe is made up of tiny particles called quarks. Normally it’s ...

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force — one of the four fundamental forces in nature, along with gravity, electromagnetism, and the ...

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...

Our account of the strong nuclear force is full of imaginative terms. Six flavors of quarks have color charges of red, green and blue, which dictate how they bind to form particles like protons and ...

Yale physicist Helen Caines has arrived at a key juncture in her long campaign to understand the “critical point” and the “strong force” of nuclear matter. In the subatomic realm, the universe’s ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

NEWPORT NEWS, VA – Much ado was made about the Higgs boson when this elusive particle was discovered in 2012. Though it was touted as giving ordinary matter mass, interactions with the Higgs field ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...
