Realizing string breaking dynamics in a lattice gauge theory on quantum hardware
Constantia Alexandrou, Andreas Athenodorou, Kostas Blekos +2
We investigate static and dynamical aspects of string breaking in a lattice gauge theory coupled to Kogut-Susskind staggered fermions. Using Tensor Network simulations, we de…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present results on the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson twisted-mass cl…
Investigation of contributions to nucleon matrix elements
Constantia Alexandrou, Giannis Koutsou, Yan Li +2
We investigate an improved method to extract nucleon matrix elements from lattice 3-point functions using a generalized eigenvalue problem (GEVP) with nucleon and pion-nucleon inte…
Investigation of pion-nucleon contributions to nucleon matrix elements
Constantia Alexandrou, Giannis Koutsou, Yan Li +2
We investigate contributions of excited states to nucleon matrix elements computed in lattice QCD by employing, in addition to the standard nucleon interpolating operator, pion-nuc…
