What does "very hard" mean here? e.g., the math is advanced? The calculations are onerous? You need too many potentially risky assumptions? etc.

- Koshkin 5y agoGood question. According to Wikipedia, Numerical lattice QCD calculations using Monte Carlo methods can be extremely computationally intensive.
- davrosthedalek 5y agoYeah, for form factors at small Q^2, you need large lattices and the convergence isn't very good --> very computational intensive.
- evanb 5y agoI am a LQCD practitioner. “Very hard” means that even with a nontrivial fraction of all the available leadership-class supercomputing in the world we don’t have enough computer power.
