Searching for new particle: Discovering axions could help answer one of the most puzzling questions in physics
From Phys.org. June 9, 2023: A team of theoretical physicists led by University of Minnesota Twin Cities has discovered a new way to search for axions, hypothetical particles to help explain “Strong CP Problem”, a puzzling phenomenon in which neutrons do not interact with electric fields despite being made up of quarks. The team worked with experimental researchers at Fermilab and this new strategy opens up previously unexplored opportunities to detect axions in particle collider experiments.
