Parity Violating Deep Inelastic Scattering Program with SoLID at Jefferson Lab

ORAL

Abstract

The solenoidal large intensity device (SoLID) is a new experimental apparatus that is planned to be constructed and installed in Jefferson Lab's Hall A facility. With its full azimuthal coverage and high luminosity capability (up to 1039 cm-2 s-1 ), the SoLID apparatus will take full advantage of the 12 GeV upgrade of the Continuous Electron Beam Accelerator Facility (CEBAF). The current program includes a set of approved experiments that will cover topics in the three-dimensional structure of the nucleon, near-threshold photo-production and electroproduction of the J/ψ meson, and fundamental symmetry studies through parity-violating deep inelastic scattering (PVDIS). The SoLID PVDIS program will measure to high precision the parity-violating asymmetry (APV) over a wide kinematic range. Utilizing a deuterium target, the PVDIS program will determine the effective electron-quark neutral couplings to test the Standard Model and to search for Beyond-the-Standard Model(BSM) physics. The deuteron measurement will also be capable of studying charge symmetry violation (CSV) and higher-twist effects. Additionally, measuring APV from hydrogen will provide a method of extracting the Parton Distribution Function (PDFs) ratio d/u at large Bjorken x, free of nuclear effects. In this presentation, I will give a brief overview of the SoLID program while focusing on its potential impact on PVDIS physics.
