Abstract

The main goal of the SPASCHARM experiment is the systematic study of spin phenomena at intermediate energies. For this purpose, it is planned to create a beam of polarized protons and antiprotons. The research includes, among other things, the study of elastic scattering. Some of the required equipment for polarimetry is planned to be also used to study elastic scattering immediately after the creation of such a channel. In this work, a set of observables necessary for model-free reconstruction of elastic proton–proton scattering amplitudes is investigated and determined.

在 U-70 的 SPASCHARM 设备上重建与模型无关的 pp 弹性散射矩阵振幅的可行性

摘要 SPASCHARM 实验的主要目标是系统研究中等能量下的自旋现象。为此，计划制造一束极化质子和反质子。这项研究主要包括弹性散射研究。极化测量所需的一些设备也计划在建立这样一个通道后立即用于研究弹性散射。在这项工作中，研究并确定了无模型重建质子-质子弹性散射振幅所需的一组观测值。

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
