'Strong CP Problem' Is Most Underrated Puzzle in Physics | RealClearScience If you ask a physicist what the biggest unsolved problem facing the field today is, you're likely to get a variety of ...

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics--the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong ...

One of the most high-profile mysteries in physics today is what scientists refer to as the “Strong CP Problem.” Stemming from the puzzling phenomenon that neutrons do not interact with electric fields ...

A new paper published in Physical Review Letters explains the theoretical model. Scientists from CERN have proposed a theory that explains the small mass of the Higgs boson and solves a problem with ...

Physicists often ponder in an unusual way: they use one unsolved problem as a hypothetic solution to another, in the hope of resolving both. The strong CP problem is the perfect example. In the ...
