July 20 , 2025 16 hrs 0 min 6 0
  • The HAYSTAC (Haloscope at Yale Sensitive to Axion Cold Dark Matter) experiment is a leading research initiative aimed at detecting axions.
  • These hypothetical particles are considered promising candidates for dark matter.
  • HAYSTAC has reported the most extensive search for axions to date, employing innovative techniques to enhance sensitivity.
  • Axions are the hypothetical elementary particles proposed to resolve a major inconsistency in particle physics known as the strong CP problem.
  • They are neutral (no electric charge) and are believed to have extremely small mass.
  • The CP symmetry refers to the combined transformation of “C (Charge): Switching particles with their antiparticles” and “P (Parity): Reversing spatial coordinates (like a mirror image)”.
