A New SRC Measurement with Polarized Deuteron Beam: Preparation Status, Maria Patsyuk (ЛФВЭ ОИЯИ),

Видеозапись общелабораторного семинара ЛФВЭ “A New SRC Measurement with Polarized Deuteron Beam: Preparation Status”, который состоялся 13 декабря 2024г. Докладчик: Maria Patsyuk (LHEP, JINR) Аннотация Short-Range Correlations (SRC) pairs form when two nucleons come into close proximity within a nucleus. Extensive studies of electron scattering have shown that most SRC pairs exhibit quantum numbers characteristic of a deuteron. Tensor-polarized deuteron studies offer a unique opportunity to explore fundamental aspects of SRC pairs, which are crucial for understanding nuclear systems, from atomic nuclei to neutron stars. An experiment using a tensor-polarized deuteron beam and a liquid hydrogen target at the Hyper-NIS experimental area has been approved by the 59th PAC. This study focuses on the hard quasi-elastic d(p,2p)n deuteron breakup reaction in SRC kinematics, aiming to ex-tract polarization observables. The results will address key challenges in high-energy and nuclear physics, including the relativistic description of bound systems, the S- to D-wave ratio in deuteron, final-state interactions (FSI) in the high-momentum regime, and the non-nucleonic components of the deuteron in polarization measurements. This talk out-lines the current status of the experimental plans and preparation.
