  • Baryon spectrum using Nf=2+1+1 ensembles of twisted mass fermions 

    Alexandrou, C; Drach, V; Hadjiyiannakou, K; Jansen, K; Kallidonis, C; Koutsou, G (2014-12-02)
    We present results on the masses of the low-lying baryons using ten ensembles of gauge configurations with $N_f =2+1+1$ dynamical twisted mass fermions, at three values of the lattice spacing, spanning a pion mass range ...
  • Baryon spectrum with $N_f=2+1+1$ twisted mass fermions 

    Alexandrou, C; Drach, V; Jansen, K; Kallidonis, C; Koutsou, G (2014-06-17)
    The masses of the low lying baryons are evaluated using a total of ten ensembles of dynamical twisted mass fermion gauge configurations. The simulations are performed using two degenerate flavors of light quarks, and a ...
  • Nucleon form factors and moments of generalized parton distributions using $N_f=2+1+1$ twisted mass fermions 

    Alexandrou, C; Constantinou, M; Dinter, S; Drach, V; Jansen, K; Kallidonis, C; Koutsou, G (2013-03-24)
    We present results on the axial and the electromagnetic form factors of the nucleon, as well as, on the first moments of the nucleon generalized parton distributions using maximally twisted mass fermions. We analyze two ...
  • Nucleon generalized form factors with twisted mass fermions 

    Alexandrou, C; Constantinou, M; Drach, V; Jansen, K; Kallidonis, C; Koutsou, G (2013-12-10)
    We present results on the nucleon form factors, momentum fraction and helicity moment for $N_f=2$ and $N_f=2+1+1$ twisted mass fermions for a number of lattice volumes and lattice spacings. First results for a new $N_f=2$ ...
  • Nucleon Structure using lattice QCD 

    Alexandrou, C; Constantinou, M; Drach, V; Hatziyiannakou, K; Jansen, K; Kallidonis, C; Koutsou, G; Leontiou, T; Vaquero, A (2013-03-27)
    A review of recent nucleon structure calculations within lattice QCD is presented. The nucleon excited states, the axial charge, the isovector momentum fraction and helicity distribution are discussed, assessing the methods ...
