Towards more accurate and form factors
Logan Roberts, Chris Bouchard, Olmo Francesconi +1
We present progress on the calculation of scalar, vector, and tensor form factors for the following meson decays: , , and $D_s\righ…
From square plaquettes to triamond lattices for SU(2) gauge theory
Ali H. Z. Kavaki, Randy Lewis
Lattice gauge theory should be able to address significant new scientific questions when implemented on quantum computers. In practice, error-mitigation techniques have already all…
Spectral-weight sum rules for the hadronic vacuum polarization
Diogo Boito, Maarten Golterman, Kim Maltman +1
We develop a number of sum rules comparing spectral integrals involving judiciously chosen weights to integrals over the corresponding Euclidean two-point function. The application…
Self-mitigating Trotter circuits for SU(2) lattice gauge theory on a quantum computer
Sarmed A Rahman, Randy Lewis, Emanuele Mendicelli +1
Quantum computers offer the possibility to implement lattice gauge theory in Minkowski rather than Euclidean spacetime, thus allowing calculations of processes that evolve in real…
Form factors of and a determination of with Möbius domain-wall-fermions
Brian Colquhoun, Shoji Hashimoto, Takashi Kaneko +1
Using a fully relativistic lattice fermion action, we compute the form factors of the semileptonic decay , which is required for the determination of the Cabibbo-Kobaya…
Diquark properties from full QCD lattice simulations
Anthony Francis, Philippe de Forcrand, Randy Lewis +1
We study diquarks on the lattice in the background of a static quark, in a gauge-invariant formalism with quark masses down to almost physical . We determine mass differences…
