Coupling of order-parameter modes withl>~1to zero sound inHe3-B

The frequencies of $B$-phase order-parameter modes are calculated with $l>~1$ pairing interactions and all Landau parameters included. The two modes that have been observed are modified by $v_3$ and the $l=2\mathrm{}$ Landau parameters. The corrections from $v_3$ and $F_2^a$ can explain the observed frequency and temperature dependence of the 2+ mode (real squashing mode). A new mode with $J=4\mathrm{}$, whose frequency depends on $v_3$, $v_5$, and $F_4^s$, may be observable in the zerosound dispersion.
