[Formula Presented]-odd interaction of axion with matter

Research output: Contribution to journalArticle


In a world with an axion the precise measurement of gravitational forces and checks of the equivalence principle at small distances, (Formula presented) and less, could provide an additional test of (Formula presented) symmetry. Using the chiral approach, we connect the strength of the (Formula presented)-odd axion-nucleon vertex with the (Formula presented)-odd pion-nucleon coupling for color electric dipole moments of quarks as a low-energy source of (Formula presented) violation. Strong limits on (Formula presented)-odd coupling (Formula presented) coming from atomic electric dipole moments give the best limits on the long range force mediated by axions, (Formula presented).
