Gender Issues in Fundamental Physics: a Bibliometric Analysis

We analyse bibliometric data about fundamental physics world-wide from 1970 to now extracting quantitative data about gender issues. We do not find significant gender differences in hiring rates, hiring timing, career gaps and slowdowns, abandonment rates, citation and self-citation patterns. Furthermore, various bibliometric indicators (number of fractionally-counted papers, citations, etc) exhibit a productivity gap at hiring moments, at career level, and without integrating over careers. The gap persists after accounting for confounding factors and manifests as an increasing fraction of male authors going from average to top authors in terms of bibliometric indices, with a quantitative shape that can be fitted by higher male variability.
