Nucleon axial and pseudoscalar form factors from lattice QCD at the physical point
C. Alexandrou, S. Bacchio, M. Constantinou +8
We compute the nucleon axial and induced pseudoscalar form factors using three ensembles of gauge configurations, generated with dynamical light quarks with mass tuned to approxima…
Lattice meets lattice: Application of lattice cubature to models in lattice gauge theory
Tobias Hartung, Karl Jansen, Frances Y. Kuo +3
High dimensional integrals are abundant in many fields of research including quantum physics. The aim of this paper is to develop efficient recursive strategies to tackle a class o…
Dimensional Expressivity Analysis of Parametric Quantum Circuits
Lena Funcke, Tobias Hartung, Karl Jansen +2
Parametric quantum circuits play a crucial role in the performance of many variational quantum algorithms. To successfully implement such algorithms, one must design efficient quan…
Lattice continuum-limit study of nucleon quasi-PDFs
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +6
The quasi-PDF approach provides a path to computing parton distribution functions (PDFs) using lattice QCD. This approach requires matrix elements of a power-divergent operator in…
Flavor decomposition for the proton helicity parton distribution functions
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +2
We present, for the first time, an \textit{ab initio} calculation of the individual up, down and strange quark helicity parton distribution functions for the proton. The calculatio…
Unpolarized and helicity generalized parton distributions of the proton within lattice QCD
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
We present the first calculation of the -dependence of the proton generalized parton distributions (GPDs) within lattice QCD. Results are obtained for the isovector unpolarized…
