Hall C will host the Hall C Summer Workshop Aug. 15-16.
Center for Theoretical and Computational Physics
Elastic electron scattering measures the transverse spatial densities of charge and magnetization in the proton and neutron, which are expressions of their microscopic quark structure governed by Quantum Chromodynamics, the fundamental theory of strong interactions. Recent theoretical work has shown that the transverse densities in the nucleon's periphery result from long-range pion exchange forces and can be computed systematically using modern methods of effective field theory. This new approach gives a precise meaning to the notion of the nucleon's "pion cloud," explains the properties of the peripheral densities from first principles, and relates them to other structures measured in high-energy inelastic scattering experiments.

Texting While Driving Now Illegal in Virginia
Texting or reading text messages while driving is now a primary offense, meaning that law enforcement can now stop you specifically for this offense. The new law also has increased penalties: a conviction will carry a $125 fine for the first offense and $250 for the second or subsequent offenses. Commercial driver license holders can be fined up to $2,750 for texting while driving or while stopped in traffic in a commercial vehicle.
