Nucleon form factors from Nf=2+1+1 twisted mass fermions at the physical point
May 29, 2019
In this proceedings we present results on the nucleon electromagnetic and axial form factors of both the connected and disconnected light and strange quarks contributions. The simulations are performed using a large volume ensemble (5.12 fm) ensemble of Nf=2+1+1 twisted mass fermions with a clover term, and the quark masses fixed to their physical values. Various analysis techniques such as the single-state, two-state and summation fits have been employed to control possible excited states contamination. The momentum dependence of the electromagnetic form factors is fitted to extract the magnetic moment and the electric and magnetic radii.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
