This study addresses various aspects of diversity in high energy physics through a scientometric analysis of the literature spanning approximately three decades, from the LEP and Tevatron era to the LHC era. It concerns both fundamental physics and technological research related to high energy physics, and compares the evolution of some diversity parameters in this field with that in other research domains, such as nuclear physics and astrophysics. The data are collected from the Web of Science and are analyzed by means of econometric methods and techniques pertaining to statistical ecology.
