Proton and neutron electromagnetic form factors from lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +5
The electromagnetic form factors of the proton and the neutron are computed within lattice QCD using simulations with quarks masses fixed to their physical values. Both connected a…
Simulating twisted mass fermions at physical light, strange and charm quark masses
Constantia Alexandrou, Simone Bacchio, Panagiotis Charalambous +11
We present the QCD simulation of the first gauge ensemble of two degenerate light quarks, a strange and a charm quark with all quark masses tuned to their physical values within th…
Multigrid approach in shifted linear systems for the non-degenerated twisted mass operator
Constantia Alexandrou, Simone Bacchio, Jacob Finkenrath
Application of multigrid solvers in shifted linear systems is studied. We focus on accelerating the rational approximation needed for simulating single flavor operators. This is pa…
