$\mathsf{Mn_{3}Sn}$ has recently attracted considerable attention as amagnetic Weyl semimetal exhibiting concomitant transport anomalies at roomtemperature. The topology of the electronic bands, their relation to themagnetic ground state and their nonzero Berry curvature lie at the heart of theproblem. The examination of the full magnetic Hamiltonian reveals otherwisehidden aspects of these unusual physical properties. Here, we report the fullspin wave spectra of $\mathsf{Mn_{3}Sn}$ measured over a wide momentum - energyrange by the inelastic neutron scattering technique. Using a linear spin wavetheory, we determine a suitable magnetic Hamiltonian which not only explainsthe experimental results but also stabilizes the low-temperature helical phase,consistent with our DFT calculations. The effect of this helical ordering ontopological band structures is further examined using a tight-binding method,which confirms the elimination of Weyl points in the helical phase. Our workprovides a rare example of the intimate coupling between the electronic andspin degrees of freedom for a magnetic Weyl semimetal system.
