      First principles calculations of nucleon and pion form factors: Understanding the building blocks of nuclear matter from lattice QCD 

      Alexandrou, Constantia; Bistrovic, B.; Edwards, R. G.; De Forcrand, P.; Fleming, G.; Hägler, P.; Negele, J. W.; Orginos, K.; Pochinsky, A.; Renner, D. B.; Richards, D. G.; Schroers, W.; Tsapalis, Antonios (2005)
      Lattice QCD is an essential complement to the current and anticipated DOE-supported experimental program in hadronic physics. In this paper we address several key questions central to our understanding of the building ...

      Precision study of excited state effects in nucleon matrix elements 

      Dinter, S.; Alexandrou, Constantia; Constantinou, Martha G.; Drach, V.; Jansen, K.; Renner, D. B. (2011)
      We present a dedicated analysis of the influence of excited states on the calculation of nucleon matrix elements. This calculation is performed at a fixed value of the lattice spacing, volume and pion mass that are typical ...

      A stochastic method for computing hadronic matrix elements 

      Alexandrou, Constantia; Constantinou, Martha; Dinter, S.; Drach, V.; Jansen, K.; Hadjiyiannakou, Kyriakos; Renner, D. B. (2014)
      We present a stochastic method for the calculation of baryon three-point functions that is more versatile than the typically used sequential method. We analyze the scaling of the error of the stochastically evaluated ...
