Query: Zero-field 29Si nuclear magnetic resonance signature of helimagnons in
  MnSi   The low temperature dependence of the nuclear magnetic resonance frequency
and spin-lattice relaxation rate measured in the chiral magnet MnSi by Yasuoka
and coworkers [J. Phys. Soc. Jpn. 85, 073701 (2016)] is interpreted in terms of
helimagnon excitations. The theoretically predicted gapless and anisotropic
dispersion relation which is probed at extremely small energy is experimentally
confirmed. Whenever comparison is possible, the results are found
quantitatively consistent with those of the inelastic neutron scattering and
muon spin rotation and relaxation techniques. Further studies are suggested.
