Recent results on nucleon sigma terms in lattice QCD

Understand

It has proven a significant challenge to experiment and phenomenology to extract precise values of the nucleon sigma terms.

• This difficulty opens the window for lattice QCD simulations to lead the field in resolving this aspect of nucleon structure.
• Here we report on recent advances in the extraction of nucleon sigma terms in lattice QCD.
• In particular, the strangeness component is now being resolved to a precision that far surpasses best phenomenological estimates.
