Title: Observation of $D^{+} \to f_{0} (500) e^{+} ν_{e}$ and Improved Measurements of $D \to ρ e^{+} ν_{e}$

Abstract

Utilizing a data sample corresponding to an integrated luminosity of 2.93 fb^-1 recorded by the BESIII detector at a center-of-mass energy of 3.773 GeV, we present an analysis of the decays D⁰→π^-π⁰e⁺v_e and D⁺→π^-π⁺e⁺v_e . Using a partial wave analysis, the π⁺π^- S-wave contribution to D⁺→π^-π⁺e⁺v_e is observed for the first time besides the dominant P-wave contribution; the statistical significance is greater than 10σ with its measured fraction (25.7 ± 1.6 ± 1.1)%. We measure the branching fractions $$\mathcal{B(D^0→p^-e^+v_e)}$$ = (1.445 ± 0.058 ± 0.039) × 10^-3, $$\mathcal{B(D^+→p^0e^+v_e)}$$ = (1.860 ± 0.070 ± 0.061) × 10^-3 and $$\mathcal{B(D^+→f_0(500)e^+v_e)}$$, f₀(500)→ π⁺π^-) = (6.30 ± 0.43 ± 0.32) × 10^-4. An upper limit of $$\mathcal{B(D^+→f_0(980)e^+v_e)}$$, f₀(980)→π⁺π^-) < 2.8 × 10^-5 is set at the 90% confidence level. We also obtain the hadronic form factor ratios of D→ρe⁺v_e at q² = 0 assuming the single-pole dominance parameterization: r_v= {[V(0)]/[A₁(0)]} = 1.695 ± 0.083 ± 0.051, r₂ = {[A₂(0)]\[A₁(0)]} = 0.845 ± 0.056 ± 0.039.

  abstractNote = {Utilizing a data sample corresponding to an integrated luminosity of 2.93 fb-1 recorded by the BESIII detector at a center-of-mass energy of 3.773 GeV, we present an analysis of the decays D0→π-π0e+ve and D+→π-π+e+ve . Using a partial wave analysis, the π+π- S-wave contribution to D+→π-π+e+ve is observed for the first time besides the dominant P-wave contribution; the statistical significance is greater than 10σ with its measured fraction (25.7 ± 1.6 ± 1.1)%. We measure the branching fractions $\mathcal{B(D^0→p^-e^+v_e)}$ = (1.445 ± 0.058 ± 0.039) × 10-3, $\mathcal{B(D^+→p^0e^+v_e)}$ = (1.860 ± 0.070 ± 0.061) × 10-3 and $\mathcal{B(D^+→f_0(500)e^+v_e)}$, f0(500)→ π+π -) = (6.30 ± 0.43 ± 0.32) × 10-4. An upper limit of $\mathcal{B(D^+→f_0(980)e^+v_e)}$, f0(980)→π+π -) < 2.8 × 10-5 is set at the 90% confidence level. We also obtain the hadronic form factor ratios of D→ρe+ve at q2 = 0 assuming the single-pole dominance parameterization: rv = {[V(0)]/[A1(0)]} = 1.695 ± 0.083 ± 0.051, r2 = {[A2(0)]\[A1(0)]} = 0.845 ± 0.056 ± 0.039.},
