Triangle Nuclear Theory Colloquium - Baryon Charges from Lattice QCD

Baryon Charges from Lattice QCD - How do quarks account for the mass, spin and distribution of momenta within a baryon? Calculating baryon charges from Lattice QCD is key to answering the question 'How do quarks account for the mass, spin and distribution of momenta within a baryon?'. In this talk, I will introduce the different types of charges and then delve deeper into our own study, on the scalar charges or more precisely on the baryon octet sigma terms. To tackle the excited state contamination - one of the biggest challenges in such calculations - we investigate the effect of different multi-state fits on the sigma terms and assess systematics. In this precision calculation, the baryon octet sigma terms are simultaneously extrapolated to the physical point taking the quark mass dependence, lattice spacing and finite volume effects into account.
