Abstract

A procedure is described for finding nonpolarized transverse, longitudinal, and polarized longitudinal-transverse and longitudinal-transverse structure functions derived from data on the differential cross sections of exclusive channels of π⁺n and π⁰p electroproduction measured with the CLAS detector. The measured cross sections cover the wide kinematic range of W < 1.7 GeV in terms of invariant mass of a finite hadronic system and photon virtuality in the range of Q² < 5.0 GeV². The exclusive structure functions obtained from a single pion production channel play an important role in studying the structure of excited nucleon states.

使用 CLAS 探测器测量的数据的电生产独有的 π+ n 和 π0 p 通道的结构函数

摘要

描述了一种用于查找非极化横向、纵向和极化纵向-横向和纵向-横向结构函数的程序，这些函数源自使用 CLAS 探测器测量的 π ⁺ n和 π ⁰ p电生产的专用通道的差分横截面的数据。在有限强子系统的不变质量和Q ² < 5.0 GeV ²范围内的光子虚拟性方面，测量的横截面覆盖了 W < 1.7 GeV 的宽运动学范围。从单个π介子产生通道获得的专有结构函数在研究激发核子态的结构中起着重要作用。
