THEORETICAL AND COMPUTATIONAL PHYSICS
Meson-Meson Scattering in Lattice Quantum Chromodynamics The determination of resonance properties of hadrons is a major focus of experiments in Halls B and D at Jefferson Lab, as well as worldwide. The Hadron Spectrum Collaboration has been using lattice Quantum Chromodynamics methods to calculate πK elastic scattering amplitudes. In two recent papers, they have investigated πK elastic scattering, searching for a resonance in the S-wave channel, and πω and πϕ scattering, in which the b₁ resonance was observed.
ESH&Q April is Distracted Driver Awareness Month We’ve all heard it before; Don’t text and drive. The National Safety Council recognizes Distracted Driving Awareness Month in April because of the staggering number of lives regularly lost due to distracted driving. Nine Americans die and 100 are injured in distracted driving crashes every day. Jefferson Lab prohibits distracted driving, including texting and driving, when operating company vehicles. Learn more about the policy here. EMERGENCY MANAGEMENT
Reminder! Emergency Response Training Exercises Scheduled for April 17-19 Newport News Fire Department Station 6 will be at Jefferson Lab this week to conduct emergency response training exercises. The exercises will continue today, April 18, through Friday, April 19, behind the North Access Building (Bldg. 67) and the Central Utility Plant (Bldg. 60) on the accelerator site. The event will include hands-on exercises involving transportation of chemicals. More information about the exercise scenario can be found in the full staff memo.
Staying Committed to Diversity, Equity and Inclusion The DOE Office of Science has reaffirmed their commitment to diversity, equity and inclusion in their most recent Diversity, Equity & Inclusion policy and procedures update in an effort to prevent harassment and discrimination and to improve workplace relations. Jefferson Lab is committed to these initiatives showcased through our Diversity and Inclusion Council. To learn more about the council initiatives, click here.
