Columbia professors contributed to new research that seeks to understand an anomaly that has puzzled particle physics for ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the ...

Deep underground in southern China, there is a 20,000-ton tank of liquid that can detect neutrinos. Named JUNO, the ...

Everything you see around you—your phone, your cat, the Earth, the stars—makes up just 15% of the mass in the universe. The ...

What was once the leading explanation for dark matter may have simply been underestimating the mass of the particles that ...

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

Until recently, scientists had never detected black holes in the “mass gap”—now, particle physicists are exploring ideas beyond the Standard Model that could explain them. On May 21, 2019, a ripple in ...

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “When are you going to find something?” Resisting the temptation to sarcastically ...

If you’ve heard the news about the Nobel Prize in physics, you might be asking yourself: What is a Higgs boson anyway? If you know one thing about the Higgs boson, it’s probably that it’s called the ...

In the late 1980s, a pair of Russian physicists put forward a new theory that just might serve to unite all physics in one model. But it’s so fiendishly complicated that decades later, few physicists ...
