Future Requirements of Lattice Field Theory Calculations on European High-Performance Computing Facilities
Gert Aarts, Gunnar Bali, Jacob Finkenrath +4
Lattice field theory provides a first-principles framework for studying properties of strongly interacting quantum field theories in elementary particle physics. Researchers in lat…
Inclusive decays from lattice QCD: computational strategy and a first physical result
Alessandro De Santis, Antonio Evangelista, Gael Finauri +16
We present a strategy to compute the inclusive decay rate for the process from first principles in lattice QCD. The physical decay rate i…
Emergence of the Resonance from Lattice QCD
Haobo Yan, Maxim Mai, Marco Garofalo +6
The mass of the lightest hadron in nature, the pion, is one seventh of that of the nucleon and one tenth of the mass of its first excited state, the . This enormous energ…
A Finite-Volume Scheme for the Continuum Extrapolation of Lattice Step-Scaling in (2+1)D Hamiltonian U(1) Gauge Theory
Alessio Negro, Emil Otis Rosanowski, Lena Funcke +4
We propose a finite-volume scheme to perform controlled continuum extrapolations of the lattice step-scaling function, a key ingredient for determining the running coupling in a Ha…
The Lambda 1405 at the point in lattice QCD
Javier Suarez Sucunza, Thomas Luu, Carsten Urbach
The pole structure of the has been a topic of debate for a long time. Chiral perturbation theory predicts that its experimental spectrum may be explained by a two pole s…
A Comprehensive Stress Test of Truncated Hilbert Space Bases against Green's function Monte Carlo in U(1) Lattice Gauge Theory
Timo Jakobs, Marco Garofalo, Tobias Hartung +5
A representation of Lattice Gauge Theories (LGT) suitable for simulations with tensor network state methods or with quantum computers requires a truncation of the Hilbert space to…
