A first look at Structured-Multiscale Algebraic Multigrid for Lattice Field Theory
Pauline Schauerte, Jaime Fabián Nieto Castellanos, Jaime Fabián Nieto Castellanos +3
State-of-the-art solvers for the Dirac equation in Lattice QCD are based on adaptive multigrid methods. These require fine-tuning of many algorithmic parameters to achieve optimal…
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…
Exotics in the system
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
In this proceedings we consider several states, namely the , , and , which appear to defy description as simple quark-ant…
Confirmation of the existence of an exotic state in the system
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
In recent years many candidates for states beyond the most simple realization of the quark model were found in various experiments around the world. However, so far no consensus ex…
Exclusion of a diquark-antidiquark structure for the lightest positive-parity charmed mesons
Eric B. Gregory, Feng-Kun Guo, Christoph Hanhart +2
The nature of low-lying scalar and axial-vector charmed mesons has been debated for decades, with hadronic molecular and compact tetraquark models being prominent candidates. These…
