Electromagnetic form factor of the pion from twisted-mass lattice QCD at Nf=2
R. Frezzotti, V. Lubicz, S. Simula
We present a lattice calculation of the electromagnetic form factor of the pion obtained using the tree-level Symanzik improved gauge action with two flavors of dynamical twisted W…
How reliable are bound-state parameters obtained from QCD sum rules?
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We discuss the extraction of ground-state parameters, such as decay constants and form factors, from two- and three-point dispersive sum rules, making use of a quantum-mechanical p…
Extracting Hadron Parameters from Dispersive Sum Rules
Wolfgang Lucha, D. Melikhov, S. Simula
Puzzled or surprised by the almost incredible accuracy occasionally claimed in the literature to be achievable for numerical outcomes of QCD sum-rule analyses, we scrutinized the u…
Light-cone expansion of heavy-to-light form factors
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present the results of our recent systematic study of the light-cone expansion of heavy-to-light transition form factors in a model with scalar constituents [1]. We show that th…
