摘要:

我们提出一种测量电子-正电子碰撞中产生的核子自旋极化的新方法。利用现有的径迹探测设备和支撑结构材料,通用谱仪无需硬件升级即可用作大接收度极化仪。采用该方法,核子的自旋极化可以被揭示,从而为末态粒子提供互补且精确的描述。这可能具有深远的意义,例如能够完整测定核子的类时电磁形状因子。

英文摘要:

We propose a novel approach to measure spin polarization of nucleons produced in electron--positron collisions. Using existing tracking devices and supporting structure material, general-purpose spectrometers can be utilized as a large-acceptance polarimeter without hardware upgrade. With the proposed approach, the spin polarization of nucleons can be revealed, providing a complementary and accurate description of the final-state particles. This could have far-reaching implications, such as enabling the complete determination of the time-like electromagnetic form factors of nucleons.
