| contents | A sensitivity study for the measurement of $\bar{K}_1(1270)$ decay modes is performed using semileptonic $D$-meson decays. The BESIII experiment is taken as a case study, where a simultaneous analysis of $\bar{K}_1(1270)$ decays to the four thee-body final states $K^-π^+π^-$, $K^-π^+π^0$, $K_S^0π^+π^-$, and $K_S^0π^-π^0$ is presented and a model-independent determination of \mbox{$\mathcal{B}(\bar{K}_1(1270)\to \bar Kππ)$}, without requiring detailed knowledge of intermediate resonant contributions, is proposed. |
