Measurement of the branching fractions of $ {D}^{+}\to {K}^{+}{K}^{-}{\pi }^{+}{\pi }^{+}{\pi }^{-}$, $ \varphi {\pi }^{+}{\pi }^{+}{\pi }^{-}$, $ {K}_{S}^{0}{K}^{+}{\pi }^{+}{\pi }^{-}{\pi }^{0}$, $ {K}_{S}^{0}{K}^{+}\eta $, and $ {K}_{S}^{0}{K}^{+}\omega $ decays

Using $ 20.3\text{}\text{}{\mathrm{fb}}^{-1}$ of $ {e}^{+}{e}^{-}$ collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector operating at the BEPCII collider, the branching fractions of three hadronic charm meson decays, $ {D}^{+}\to \varphi {\pi }^{+}{\pi }^{+}{\pi }^{-}$, $ {D}^{+}\to {K}_{S}^{0}{K}^{+}{\pi }^{+}{\pi }^{-}{\pi }^{0}$, and $ {D}^{+}\to {K}_{S}^{0}{K}^{+}\omega $, are measured for the first time to be $ (0.54\pm 0.19\pm 0.02)\times {10}^{-4}$, $ (2.51\pm 0.34\pm 0.14)\times {10}^{-4}$, and $ (2.02\pm 0.35\pm 0.10)\times {10}^{-4}$, respectively. Futhermore, the branching fractions of $ {D}^{+}\to {K}^{+}{K}^{-}{\pi }^{+}{\pi }^{+}{\pi }^{-}$ and $ {D}^{+}\to {K}_{S}^{0}{K}^{+}\eta $ are measured with improved precision, yielding values of $ (0.66\pm 0.11\pm 0.03)\times {10}^{-4}$ and $ (2.27\pm 0.22\pm 0.05)\times {10}^{-4}$, respectively.
