A new paper presents the first lattice QCD study of coupled isoscalar ππ, KK and ηη S- and D-wave scattering extracted from discrete finite-volume spectra using a value of the quark mass corresponding to mπ ~ 391 MeV. In the JP=0+ sector, the study finds analogues of the experimental σ and f0(980) states, where the σ appears as a stable bound-state below the ππ threshold, and, similar to what is seen in experiment, the f0(980)manifests itself as a dip in the ππ cross section in the vicinity of the KK threshold.

The Electrical Systems group continued to support ongoing maintenance in the CEBAF accelerator with work on the trim magnet system, the RF separators, an upgrade to the East Arc dump controls and repairs to the Personnel Safety System video system.
Vacuum and installation support to prepare for testing LCLS-II cryomodules in the Low Energy Recirculation Facility continued, as did the installation of the new C50-13 crymodule in the North Linac of CEBAF. The Metrology group continued survey work in the halls to support upcoming operations, as well as LCLS-II cryomodule alignment tasks and magnet maintenance in the accelerator.
A tour of Jefferson Lab and meeting for the Old Dominion University School of Engineering staff was hosted by Tim Michalski. This is a continuation of a possible collaboration to engage ODU students and faculty on the Jefferson Lab Electron-Ion Collider initiative and other engineering projects. Two engineers participated in the FS2D3 Facility for Rare Isotope Beams Magnet Design Review held at Michigan State University.
