The S-matrix pole position is ($764$ $\pm63$ ${}^{+71}_{-54}$) $−$ ${\mit i}$ ($306$ $\pm149$ ${}^{+143}_{-85}$) MeV. 2  From a fit including ten additional resonances and energy-independent Breit-Wigner width. 3  A fit in the ${{\mathit K}_{{{0}}}^{*}{(700)}}$ + ${{\mathit K}^{*}{(892)}}$ + ${{\mathit K}^{*}{(1410)}}$ model with mass and width of the ${{\mathit K}_{{{0}}}^{*}{(700)}}$ from ABLIKIM 2006C well describes the left slope of the ${{\mathit K}_S^0}$ ${{\mathit \pi}^{-}}$ invariant mass spectrum in ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit \pi}^{-}}{{\mathit \nu}_{{{\tau}}}}$ decay studied by EPIFANOV 2007. Averaged value from different parameterizations. 4  Not seen by KOPP 2001 using 7070 events of ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{0}}$. LINK 2002E and LINK 2005I show clear evidence for a constant non-resonant scalar amplitude rather than ${{\mathit K}_{{{0}}}^{*}{(700)}}$ in their high statistics analysis of ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$. 5  AUBERT 2007T does not find evidence for the charged ${{\mathit K}_{{{0}}}^{*}{(700)}}$ using 11k events of ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit K}^{+}}{{\mathit \pi}^{0}}$. 6  Using parameters from the model that fits data best. 7  Statistical error only. A fit to the Dalitz plot including the ${{\mathit K}_{{{0}}}^{*}{(700)}^{\pm}}$, ${{\mathit K}^{*}{(892)}^{\pm}}$, and ${{\mathit \phi}}$ resonances modeled as Breit-Wigners. A significant ${\mathit S}{\mathrm -wave}$ can be also modeled as a non-resonant contribution. 8  Reanalysis of ASTON 1988 using interfering Breit-Wigner amplitudes.
