Lattice determination of the neutrino background for $J / I ¨ \to I^^{3} + invisible$

Yu Meng, Ning Li, Chuan Liu +3

The paper presents the first lattice QCD calculation of the Standard Model decay J/ψ → γ ν ν̄, providing a branching fraction of about 1×10⁻¹⁰ to serve as a neutrino background ben…

Form factors of the $D_{s} \to I ¨ ℓ I^½_{ℓ}$ semileptonic decay with (2+1)-flavor lattice QCD

Gaofeng Fan, Yu Meng, Chuan Liu +5

We present a systematic lattice calculation of the vector and axial vector form factors $V$ and $A_{i} (i = 0, 1, 2)$ for the $D_{s} \to I ¨ ℓ I^½_{ℓ}$ semileptonic decay using (2+1)-flav…

First lattice QCD calculation of $J / I ¨ $ semileptonic decay containing $D$ and $D_{s}$ particles

Yu Meng, Jin-Long Dang, Chuan Liu +4

We perform the first lattice calculation on the semileptonic decay of $J / I ¨ $ using the (2+1)-flavor Wilson-clover gauge ensembles generated by CLQCD collaboration. Three gauge ense…

Lattice QCD calculation of the $D_{s}^{*}$ radiative decay with (2+1)-flavor Wilson-clover ensembles

Yu Meng, Jin-Long Dang, Chuan Liu +4

We perform a lattice calculation on the radiative decay of $D_{s}^{*}$ using the (2+1)-flavor Wilson-clover gauge ensembles generated by CLQCD collaboration. A method allowing us to ca…
