- Reasonable signals observed in gluonic mass components
- Feasibility of lattice calculations for gluonic contributions
- Highlights computational challenges with gluon fluctuations

## Abstract

About half the mass of a hadron is given from gluonic contributions. In this talk we calculate the chromo-electric and chromo-magnetic components of the nucleon mass. These computations are numerically difficult due to gluon field ultra-violet fluctuations. Nevertheless a high statistics feasibility run using quenched Wilson fermions seems to show reasonable signals.
