Hadron Form Factors at BESIII

, 2018
Form factors of hadron provide fundamental information about its structure and dynamics. They constitute a rigorous test of non-perturbative QCD as well as of phenomenological models.

N to Δ electromagnetic transition form factors from lattice QCD

, 2004
The magnetic dipole, the electric quadrupole and the Coulomb quadrupole amplitudes for the transition $\gamma N\to \Delta$ are evaluated both in quenched lattice QCD at $\beta=6.0$ and using two dynamical Wilson fermions simulated at $\beta=5.6$.

Advanced parametrisations for hadronic form factors

Journal of High Energy Physics
The rich analytic structure of hadronic form factors makes a theoretically consistent yet easily applicable parametrisation cumbersome. Consequently, most parametrisations are limited to reproducing the simplest analytic features sufficient to describe ...

Form factors in lattice QCD

, 2011
Lattice simulations of QCD have produced precise estimates for the masses of the lowest-lying hadrons which show excellent agreement with experiment.

Electroweak form factors of non-strange baryons

, 2002
We compute electroweak form factors of the nucleon and photon transition form factors of nonstrange baryon resonances up to the third resonance region in a model with instanton-induced ...

Baryon Form Factors

We review the status of baryon form factors with a special focus on the nucleon electromagnetic form factors which are known best. First, we give an introduction into the dispersive analyses and emphasize the role of unitarity and analyticity in the ...

form factors and the

In this paper we revisit $$D_s \rightarrow f_0(980)$$ form factors from the light-cone sum rules based on the $${\bar{q}}q$$ picture of $$f_0(980)$$. The main motivation of this study is the decay width of $$D_s^+ \rightarrow \left[ \pi \pi \right] _{S}^{
