The SpinQuest experiment (E1039) at Fermilab will measure the correlation between the angular distribution of the final-state di-muons and the spin-polarization of transversely polarized NH$_3$ (for proton) and ND$_3$ (for neutron) targets. The 120 GeV unpolarized proton beam of the Main Injector will be used to measure the Transverse Single Spin Asymmetry (TSSA) to quantify both the magnitude...
SpinQuest will measure the sea quarks Sivers Asymmetry, a left-right
asymmetry, with a target transversely polarized with respect to the in-
coming 120 GeV proton beam. An online monitoring system has been
developed to scan the polarized target system and polarization data while
integrating information from detectors and event reconstruction for near
continuous quality checking of the...
The E1039/SpinQuest experiment at Fermilab will measure the transverse single spin asymmetry (TSSA) in several processes such as $J/\psi$ production and Drell-Yan di-muon pair production, exploiting the 120 GeV unpolarized proton beam from the Fermilab Main Injector on transversely polarized ammonia and deuterated ammonia targets.
Such measurements are anticipated to provide knowledge on the...
Positron scattering from hadronic targets can provide new information that cannot be accessed with electron scattering alone. The asymmetry in deeply virtual Compton scattering cross sections between positrons and electrons can provide a critical handle on the Bethe-Heitler background process. A similar asymmetry in elastic scattering can reveal the contribution from two-photon exchange, which...
Extending CEBAF energy reach by increasing the number of recirculations, while using the existing SRF system is being explored. Proposed energy upgrade is based on a new approach to multi-pass acceleration of electrons in a single Fixed Field Alternating Gradient (FFA) beam line, configured with Halbach-style permanent magnets. Encouraged by recent success of CBETA, a proposal was formulated...
Spin asymmetry and cross section measurements in semi-inclusive hadroproduction grant access to a variety of parton distribution and fragmentation functions. Such measurements of dihadron production additionally constrain Dihadron Fragmentation Functions (DiFFs), and the extra degree of freedom from the second hadron facilitates access to some of the parton distribution functions. At CLAS...
Solenoidal Large Intensity Detector (SoLID) is a large acceptance, high luminosity device proposed for exploiting the full potential of the Jefferson Lab (JLab) 12 GeV energy upgrade. The scientific program of SoLID includes six approved experiments: three Semi-Inclusive Deep Inelastic Scattering (SIDIS), two Parity-Violating Deep Inelastic Scattering (PVDIS), and one $J/\psi$ production. As a...
In this talk, we will provide an overview of future parity violation deep inelastic scattering (PVDIS) experiments by using the Solenoidal Large Intensity Device (SoLID) at Jefferson Lab (JLab) Hall A. We will obtain data with high statistic and large kinematic coverage for Bjorken $0.25
The MOLLER (Measurement Of a Lepton Lepton Electroweak Reaction) experiment aims to measure the parity-violating asymmetry $A_{PV}$ in the scattering of longitudinally polarized electrons off unpolarized electrons with an uncertainty of 0.8 ppb. This measurement can be used to directly determine the weak mixing angle at low $Q^{2}$ with the best precision ($\delta(\sin^2\theta_W) = \pm...
Vector meson (VM) production in polarized quark fragmentations has been recently studied in the context of the string+${}^3P_0$ model of hadronization. The spin effects for the production of VMs depend on the coupling of the mesons to the quarks in the fragmentation chain, which is parametrized in terms of two free parameters. One of the parameters governs the fraction of longitudinally...
Lepton scattering is an established ideal tool for studying the structures of nucleons and nuclei. As a future high energy nuclear physics project, an Electron-ion collider in China (EicC) has been proposed, to be constructed based on the High Intensity heavy-ion Accelerator Facility (HIAF) which is currently under construction, together with a new electron ring. The proposed collider will...
