Abstract
The dispersion of the transverse zero sound in superfluid3He-B in the colisionless limit is studied theoretically. The dispersion is most easily understood as due to strong coupling between two distinct modes; the original zero-sound mode which is present in normal liquid and the collective mode with energy gap ω t (T) proportional to Δ(T), the temperature-dependent energy gap.
