Abstract
The interaction of the fermionic quasiparticles with bosonic collective modes in3He-A recalls the interaction of massless chiral fermions with photons, W-bosons, and gravitational waves in high-energy physics. The chiral anomaly and vacuum polarization are responsible for singular dynamics of3He-A atT=0.
