Long-distance contribution to $ε_{K}$ from lattice QCD

Ziyuan Bai, Norman H. Christ, Joseph M. Karpie +3

A lattice QCD approach to the calculation of the long-distance contributions to $ε_{K}$ is presented. This parameter describes indirect CP violation in $K \to π π$ decay. While the shor…

Higher strangeonium decays into light flavor baryon pairs like $Λ Λ ˉ$ , $Σ Σ ˉ$ , and $Ξ Ξ ˉ$

Zi-Yue Bai, Qin-Song Zhou, Xiang Liu

In this work, we investigate the decay behaviors of several higher strangeonia into $Λ Λ ˉ$ through a hadronic loop mechanism, enabling us to predict some physical observables, in…

Investigating the $Υ (10753) \to Υ (1^{3} D_{J}) η$ transitions

Yu-Shuai Li, Zi-Yue Bai, Xiang Liu

In this work, we investigate the $Υ (10753) \to Υ (1^{3} D_{J}) η$ ( $J = 1, 2, 3$ ) processes, where the $Υ (10753)$ is assigned as a conventional bottomonium under the $4 S$ - $3 D$ mixing scheme. Ou…

$Υ (10753) \to Υ (nS) π^{+} π^{-}$ decays induced by hadronic loop mechanism

Zi-Yue Bai, Yu-Shuai Li, Qi Huang +2

In this work, we investigate the $Υ (10753) \to Υ (n S) π^{+} π^{-}$ ( $n = 1, 2, 3$ ) processes by considering the hadronic loop mechanism, where $Υ (10753)$ is assigned to a conventional bottomoni…

Hidden-bottom hadronic decays of $Υ (10753)$ with a $η^{(')}$ or $ω$ emission

Yu-Shuai Li, Zi-Yue Bai, Qi Huang +1

In this work, we propose the $4 S$ - $3 D$ mixing scheme to assign the $Υ (10753)$ into the conventional bottomonium family. Under this interpretation, we further study its hidden-botto…

Exploratory lattice QCD study of the rare kaon decay $K^{+} \to π^{+} ν ν ˉ$

Ziyuan Bai, Norman H. Christ, Xu Feng +3

In Ref [1] we have presented the results of an exploratory lattice QCD computation of the long-distance contribution to the $K^{+} \to π^{+} ν ν ˉ$ decay amplitude. In the present paper…

Exploratory Lattice QCD Study of the Rare Kaon Decay $K^{+} \to π^{+} ν ν ˉ$

Ziyuan Bai, Norman H. Christ, Xu Feng +3

We report a first, complete lattice QCD calculation of the long-distance contribution to the $K^{+} \to π^{+} ν ν ˉ$ decay within the standard model. This is a second-order weak process…

Long distance part of $ε_{K}$ from lattice QCD

Ziyuan Bai

We demonstrate the lattice QCD calculation of the long distance contribution to $ε_{K}$ . Due to the singular, short-distance structure of $ε_{K}$ , we must perform a short-distance subt…

Standard-model prediction for direct CP violation in $K \to π π$ decay

Z. Bai, T. Blum, P. A. Boyle +11

We report the first lattice QCD calculation of the complex kaon decay amplitude $A_{0}$ with physical kinematics, using a $3 2^{3} \times 64$ lattice volume and a single lattice spacing…

$K_{L}$ - $K_{S}$ mass difference computed with a 171 MeV pion mass

Ziyuan Bai

In this work, we used a $3 2^{3} \times 64 \times 32$ , 2+1 flavor domain wall lattice with Iwasaki+DSDR gauge action. The pion mass is 171 MeV and the kaon mass is 492 MeV. We impleme…

$K_{L} - K_{S}$ mass difference from lattice QCD

Z. Bai, N. H. Christ, T. Izubuchi +3

We report on the first complete calculation of the $K_{L} - K_{S}$ mass difference, $Δ M_{K}$ , using lattice QCD. The calculation is performed on a 2+1 flavor, domain wall fermion ensemble…

$K_{L} - K_{S}$ mass difference from Lattice QCD

Jianglei Yu

We will report on the first full calculation of the $K_{L} - K_{S}$ mass difference in lattice QCD. The calculation is performed on a 2+1 flavor, domain wall fermion, $2 4^{3} \times 64$ ens…
