We present the first determination of x-dependent pion gluon distribution from lattice QCD using pseudo-PDF approach. use ensembles with 2+1+1 flavors highly improved staggered quarks (HISQ), generated by MILC Collaboration, at two spacings a?0.12 and 0.15 fm three masses M??220, 310 690 MeV. clover fermions for valence action momentum smearing to achieve boost up 2.29 GeV. find that dependence...

We calculate the propagator of the domain wall fermion (DWF) of the RBC/UKQCD collaboration with 2+1 dynamical flavors of 163 × 32× 16 lattice in Coulomb gauge, by applying the conjugate gradient method. We find that the fluctuation of the propagator is small when the momenta are taken along the diagonal of the 4-dimensional lattice. Restricting momenta in this momentum region, which is called ...

Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high bandwidth, low latency, and power consumption. We propose demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control which is suitable for HPC infrastructures. also present an Optimized Mapping (OPM) algorithm that maps the most communication-related processes inside rack....

In the framework of large-momentum effective theory at one-loop matching accuracy, we perform a lattice calculation Collins-Soper kernel which governs rapidity evolution transverse-momentum-dependent (TMD) distributions. We first obtain quasi TMD wave functions three different meson momenta on with valence clover quarks dynamical HISQ sea and spacing $a=0.12$~fm from MILC, renormalize pertinent...

Abstract In this work we apply the Dispersive Matrix (DM) method of Di Carlo et al. (Phys Rev D 104:054502, 2021) and Martinelli 105:034503, 2022) to lattice computations Form Factors (FFs) entering semileptonic $$B \rightarrow D^* \ell \nu _\ell $$ B → D ∗<...

We present a new Bjorken x-dependence analysis of previous lattice quantum chromodynamics data for the pion distribution amplitude from MILC configurations with three spacing a=0.06,0.09,0.12 fm. A leading renormalon resummation in renormalization as well perturbative matching kernel framework large momentum expansion generates power accuracy to light-cone amplitude. Meanwhile, small log is imp...

The MILC Collaboration We study the effects of different " fat link " actions for Kogut-Susskind quarks on flavor symmetry breaking. Our method is mostly empirical-we compute the pion spectrum with different valence quark actions on common sets of sample lattices. Different actions are compared, as best we can, at equivalent physical points. We find significant reductions in flavor symmetry bre...
