Arxiv HEP-PH (High Energy Physics - Phenomenology) collaboration network is from the e-print arXiv and covers scientific collaborations between authors papers submitted to High Energy Physics - Phenomenology category. If an author *i* co-authored a paper with author *j*, the graph contains a undirected edge from *i* to *j*. If the paper is co-authored by *k* authors this generates a completely connected (sub)graph on *k* nodes.

The data covers papers in the period from January 1993 to April 2003 (124 months). It begins within a few months of the inception of the arXiv, and thus represents essentially the complete history of its HEP-PH section.
