we observe that a transmission blockade is present only for the single mode regime (see Fig.\[fig:transmission\_t123\_boson\_fermion\] (a) red solid line). However, in the case of several open channels the transmission blockade is lifted giving in turn rise to finite values of the transmission coefficient. In addition transparency, i.e. $T_i^{(0)}=1$ occurs in the absence of interactions ($\bar{a}^{2\ell+1}_\ell=0$) between the colliding particles. Analogously, panel (b) of Fig. \[fig:transmission\_t123\_boson\_fermion\] depicts the results for $\ell=1$, as a function of the scaled $p$-wave scattering volume $(\bar{a}_1)^3$. Unlike the $s$-wave case, here the asymmetry of the line shape is barely visible if the collision energy is raised above the first excited channel threshold.

More insight into the behaviour of the transmission coefficients $T_i^{(0)}$ can be obtained from Fig. \[fig:transmission\_trend\_s\], where we present $T_0^{(0)}$ and $T_1^{(0)}$ versus $\epsilon$ in panels (a) and (b), respectively.
