NT/RBRC seminar

"The role of exotic operators in determining the finite-volume spectrum from Lattice QCD and its consequences"

Presented by Sarah Skinner, Carnegie Mellon University

Friday, August 18, 2023, 11:00 am — Large Seminar Room, Bldg. 510

Abstract: There are several methods to calculate QCD scattering information on the lattice, but one of the most popular methods is the Lüscher formalism. In this talk, I will discuss how we use the finite-volume energy spectrum and the Lüscher formalism to calculate infinite-volume scattering results, and how it may require non-intuitive methods. Using Nf?=2+1 lattice QCD for pion masses near 200 MeV, a summary of the Δ resonance calculation is reviewed, as well as quick looks at the K∗0?(700), a0?(980), deuteron, and dineutron scattering channels.
