Abstract:
Using 2.93 fb − 1 of e + e − collision data collected with the BESIII detector at the center-of-mass energy 3.773 GeV, we perform the first amplitude analysis of the decay D + → $$ {K}_S^0 $$ K S 0 π + π 0 π 0 and determine the relative magnitudes and phases of different intermediate processes. The absolute branching fraction of D + → $$ {K}_S^0 $$ K S 0 π + π 0 π 0 is measured to be (2.888 ± 0.058 stat . ± 0.069 syst . )%. The dominant intermediate processes are D + → $$ {K}_S^0 $$ K S 0 a 1 (1260) + ( → ρ + π 0 ) and D + → $$ \overline{K} $$ K ¯ *0 ρ + , with branching fractions of (8.66 ± 1.04 stat . ± 1.39 syst . ) × 10 − 3 and (9.70 ± 0.81 stat . ± 0.53 syst . ) × 10 − 3 , respectively.
