A contribution to the history of quarks: Boris Struminsky's 1965 JINR publication

TL;DR

This paper discusses Boris Struminsky's 1965 publication, which introduced the concept of an internal quantum number for quarks, laying groundwork for the color charge theory in particle physics.

Contribution

It presents a translation and analysis of Struminsky's pioneering 1965 work on quark quantum numbers, highlighting its historical significance.

Findings

Introduced the idea of quark internal quantum number

Connected quark properties to baryon magnetic moments

Historical analysis of early quark theory development

Abstract

The idea that an internal quantum number for quarks, eventually called color, can explain the magnetic moments of baryons within the framework of standard quantum theory, was explicitly stated in a 7th January, 1965 JINR publication by Boris Struminsky (JINR P-1939). A complete translation into English of Struminsky's letter is presented along with page images of the original booklet found in the JINR Library.
