Isospin 0 and 2 two-pion scattering at physical pion mass using distillation with periodic boundary conditions in lattice QCD
Mattia Bruno, Daniel Hoying, Taku Izubuchi +3
The two pion channel in Lattice QCD has long been a primary testing ground for studying multiparticle scattering in finite volume QCD. With the development of sophisticated techniq…

A study of two-pion scattering for the isospin channels, and , using lattice QCD is presented. Möbius domain wall fermions on top of the Iwasaki-DSDR gauge action for gl…
All-mode Renormalization for Tensor Network with Stochastic Noise
Erika Arai, Hiroshi Ohki, Shinji Takeda +1
In usual (non-stochastic) tensor network calculations, the truncated singular value decomposition (SVD) is often used for approximating a tensor, and it causes systematic errors. B…
Discovering new physics in rare kaon decays
Thomas Blum, Peter Boyle, Mattia Bruno +20
The decays and mixing of mesons are remarkably sensitive to the weak interactions of quarks and leptons at high energies. They provide important tests of the standard model at…

Masaaki Tomii, Thomas Blum, Daniel Hoying +4
We calculate matrix elements using periodic boundary conditions as an independent calculation from our previous study with G-parity boundary conditions. We present our pre…
Hybrid stochastic method for the tensor renormalization group
Hiroshi Ohki, Erika Arai, Masaaki Tomii
We propose a hybrid stochastic method for the tensor renormalization group (TRG) approach. TRG is known as a powerful tool to study the many-body systems and quantum field theory o…

We present a lattice QCD calculation of the , decay amplitude and , the measure of direct CP-violation in decay, improving our 2015 ca…
Towards non-perturbative matching of three/four-flavor Wilson coefficients with a position-space procedure
Masaaki Tomii
We propose a strategy to non-perturbatively match the Wilson coefficients in the three- and four-flavor theories, which uses two-point Green's functions of the corresponding four-q…
-symmetric position-space renormalization of lattice operators
Masaaki Tomii, Norman H. Christ
We extend the position-space renormalization procedure, where renormalization factors are calculated from Green's functions in position space, by introducing a technique to take th…
