Constructing Nucleon Operators on a Lattice for Form Factors with High Momentum Transfer

We present preliminary results of computing nucleon form factor at high momentum transfer using the ``boosted'' or ``momentum'' smearing. We use gauge configurations generated with $N_f=2+1 $dynamical Wilson-clover fermions and study the connected as well as disconnected contributions to the nucleon form factors. Our initial results indicate that boosted smearing helps to improve the signal for nucleon correlators at high momentum. However, we also find evidence for large excited state contributions, which will likely require variational analysis to isolate the boosted nucleon ground state.
