Title: Observation of the Semileptonic Decay $D^{0} \to a_{0} (980)^{-} e^{+} ν_{e}$ and Evidence for $D^{+} \to a_{0} (980)^{0} e^{+} ν_{e}$

Abstract

Using an e⁺e^- collision data sample of 2.93 fb^-1 collected at a center-of-mass energy of 3.773 GeV by the BESIII detector at BEPCII, we report the observation of D⁰ → a₀(980)^-e⁺ν_e and evidence for D⁺ → a₀(980)⁰e⁺ν_e with significances of 6.4σ and 2.9σ, respectively. The absolute branching fractions are determined to be B(D⁰ → a₀(980)^-e⁺ν_e) × B(a₀(980)^- → ηπ^-) = [1.33$$\mathbb +0.33\atop{-0.29}$$ (stat)±0.09(syst)] × 10^-4 and B(D⁺ → a₀(980)⁰e⁺ν_e) × B(a₀(980)⁰ → ηπ⁰) = [1.66$$\mathbb +0.81\atop{-0.66}$$(stat) ± 0.11(syst)] × 10^-4. An upper limit of B(D⁺ → a₀(980)⁰e⁺ν_e × B(a₀(980)⁰ → ηπ0) < 3.0 × 10^-4 is also determined at the 90% confidence level.

  abstractNote = {Using an e+e- collision data sample of 2.93 fb-1 collected at a center-of-mass energy of 3.773 GeV by the BESIII detector at BEPCII, we report the observation of D0 → a0(980)-e+νe and evidence for D+ → a0(980)0e+νe with significances of 6.4σ and 2.9σ, respectively. The absolute branching fractions are determined to be B(D0 → a0(980)-e+νe) × B(a0(980)- → ηπ-) = [1.33$\mathbb +0.33\atop{-0.29}$ (stat)±0.09(syst)] × 10-4 and B(D+ → a0(980)0e+νe) × B(a0(980)0 → ηπ0) = [1.66$\mathbb +0.81\atop{-0.66}$(stat) ± 0.11(syst)] × 10-4. An upper limit of B(D+ → a0(980)0e+νe × B(a0(980)0 → ηπ0) < 3.0 × 10-4 is also determined at the 90% confidence level.},

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)%.

Journal Article Ablikim, M. ; Achasov, M. N. ; Adlarson, P. ; ... - Physical Review D

Using 2.93 fb^–1 of e⁺e^– annihilation data collected at a center-of-mass energy √s = 3.773 GeV with the BESIII detector operating at the BEPCII collider, we search for the semileptonic D⁰⁽⁺⁾ decays into a b₁ (1235)^–(0) axial-vector meson for the first time. No significant signal is observed for either charge combination. The upper limits on the product branching fractions are ^BD⁰ → b₁(1235)^–e + ν_e · ^Bb₁(1235)^– → ωπ^– < 1.12 × 10^–4 and ^BD⁺ → b₁(1235)⁰e⁺ ν_e · ^Bb₁(1235)⁰ → ωπ⁰ < 1.75 × 10^–4 at the 90% confidence level.

Measurement of the Ratio of the $B^{0} \to D^{* -} τ^{+} ν_{τ}$ and $B^{0} \to D^{* -} μ^{+} ν_{μ}$ Branching Fractions Using Three-Prong $τ$ -Lepton Decays

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review Letters

The ratio of branching fractions R(D*^–) ≡ B(B⁰ → D*^–τ⁺ν_τ)/B(B⁰ → D*^–μ⁺ν_μ) is measured using a data sample of proton-proton collisions collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb^–1. For the first time, R(D*^–) is determined using the τ-lepton decays with three charged pions in the final state. The B⁰ → D*^–τ⁺ν_τ yield is normalized to that of the B⁰ → D*^–π⁺π^–π⁺ mode, providing a measurement of B(B⁰ → D*^–τ⁺ν_τ)/B(B⁰ → D*^–π⁺π^–π⁺) = 1.97 ± 0.13 ± 0.18, where the first uncertainty is statistical and the secondmore »« less
