The “White Paper” detailing the science case for a positron beam at Jefferson Lab was published to the arxiv.org preprint server on July 29. Professor Puckett authored the section on polarization transfer in positron-proton elastic scattering. The “White Paper” can be found here.

Preprint of ECT* Diquark Workshop Proceedings submitted to PPNP
The manuscript of the proceedings paper from the September 2019 ECT* “Diquark Correlations” workshop in Trento, Italy has recently been submitted for publication to Progress in Particle and Nuclear Physics. The preprint of the paper can be found at the following link. Professor Puckett gave an invited talk at the workshop and wrote the section of the paper titled “Super BigBite Spectrometer Programme on High-Q2 Space-like Nucleon Form Factors”.
Two new experiments approved by Jefferson Lab Program Advisory Committee
Two new experiments using the Super BigBite Spectrometer (SBS) have been approved by the Jefferson Lab Program Advisory Committee (PAC) at its 48th meeting.
The goal of the first experiment (E12-20-010), with UConn postdoc Eric Fuchey as co-spokesperson and contact person, is to perform the first precise measurement of the so-called “Rosenbluth slope” in the elastic electron-neutron scattering cross section at a large momentum transfer, to determine whether there are significant contributions to this process beyond the dominant single-photon-exchange contribution, as is already well established for elastic electron-proton scattering. The PAC approved this experiment for two days of new beam time with a scientific rating of “A-“.

The goal of the second experiment (E12-20-008), with Professor Puckett as co-spokesperson and contact person, is to perform a first measurement of the polarization transfer observables in the photoproduction of charged pions in the reaction γ+n → π–+p at high energies and wide scattering angles in the center-of-mass frame. These measurements can unambiguously test predictions based on the framework of Generalized Parton Distributions (GPDs). The PAC approved this experiment for two days of new beam time with a scientific rating of “B+”.
