Semileptonic decays of doubly charmed baryons with $Ξ_{c} - Ξ_{c}^{'}$ mixing

Chao-Qiang Geng, Xian-Nan Jin, Chia-Wei Liu +2

We study the $Ξ_{c} - Ξ_{c}^{'}$ mixing effects in the semileptonic decays the doubly charm baryons of $Ξ_{cc}$ . We focus on the ratio of ${\cal R}(θ_c) \equiv {\cal B}( Ξ_{cc} \to Ξ_c' e^…

(Nearly) Model-Independent Constraints on the Neutral Hydrogen Fraction in the Intergalactic Medium at $z \sim 5 - 7$ Using Dark Pixel Fractions in Ly $α$ and Ly $β$ Forests

Xiangyu Jin, Jinyi Yang, Xiaohui Fan +10

Cosmic reionization was the last major phase transition of hydrogen from neutral to highly ionized in the intergalactic medium (IGM). Current observations show that the IGM is sign…

Heavy quark symmetry of $Λ_{b}^{0}$ decays in quark models

Jiabao Zhang, Xiang-Nan Jin, Chia-Wei Liu +1

We study the heavy quark symmetry with the homogeneous bag model (HBM) and light-front quark model (LFQM) based on the decays of $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} ν_{ℓ} (ℓ = e, μ, τ)$ .…

Anatomy of $Λ_{c}^{+}$ semileptonic decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu

We present a systematic study of $Λ_{c}^{+} \to B_{q} ℓ^{+} ν_{ℓ}$ with $B_{q} = (Λ, n)$ and $ℓ = (e, μ)$ , examining all the possible decay observables based on the hom…

Resolving puzzle in $Ξ_{c}^{0} \to Ξ^{-} e^{+} ν_{e}$ with $Ξ_{c} - Ξ_{c}^{'}$ mixing

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu

We study the ratio of $R = 2Γ (Ξ_{c}^{0} \to Ξ^{-} e^{+} ν_{e}) /3Γ (Λ_{c}^{+} \to Λ e^{+} ν_{e})$ , which is found to be $R = 1 (0.8)$ from the exact (broken) $S U (3)$ flavor symmetry, in sharp contrast…

Time-reversal asymmetries in $Λ_{b}$ semileptonic decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu

We study the decays of $Λ_{b} \to Λ_{c} (\to B_{n} f) ℓ^{-} ν$ with $ℓ = e, μ, τ$ , where $B_{n}$ and $f$ are the daughter baryons and the rest of the particles in $Λ_{c}$ cascad…

New extraction of CP violation in b-baryon decays

Chao-Qiang Geng, Xiang-Nan Jin, Chia-Wei Liu +2

We study CP violation in b-baryon decays of $Ξ_{b}^{-} \to Ξ^{-} D$ with $D = D^{0}, D ˉ^{0}$ and $D_{i} (i = 1, 2)$ . We find that these baryonic decay processes provide an ideal opportunity…
