Abstract

A bstract An amplitude analysis of the Cabibbo-favored decay D + → K − π + π + π 0 is performed, using 7.93 fb − 1 of e + e − collision data collected with the BESIII detector at the center-of-mass energy of 3.773 GeV. The branching fractions of the intermediate processes are measured, with the dominant contribution $$ {D}^{+}\to {\overline{K}}^{\ast }{(892)}^0\rho {(770)}^{+} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mi>D</mml:mi> <mml:mo>+</mml:mo> </mml:msup> <mml:mo>→</mml:mo> <mml:msup> <mml:mover> <mml:mi>K</mml:mi> <mml:mo>¯</mml:mo> </mml:mover> <mml:mo>∗</mml:mo> </mml:msup> <mml:msup> <mml:mfenced> <mml:mn>892</mml:mn> </mml:mfenced> <mml:mn>0</mml:mn> </mml:msup> <mml:mi>ρ</mml:mi> <mml:msup> <mml:mfenced> <mml:mn>770</mml:mn> </mml:mfenced> <mml:mo>+</mml:mo> </mml:msup> </mml:math> observed to have a branching fraction of (4.35 ± 0.07 stat . ± 0.17 syst . )%.
