High-energy physics theory citation network

Dataset information

Arxiv HEP-TH (high energy physics theory) citation graph is from the e-print arXiv and covers all the citations within a dataset of 27,770 papers with 352,807 edges. If a paper i cites paper j, the graph contains a directed edge from i to j. If a paper cites, or is cited by, a paper outside the dataset, the graph does not contain any information about this.

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-TH section.

The data was originally released as a part of 2003 KDD Cup.

Paper: hep-th/0002031 From: Maulik K. Parikh Date: Fri, 4 Feb 2000 17:04:51 GMT (10kb) Title: Confinement and the AdS/CFT Correspondence Authors: D. S. Berman and Maulik K. Parikh Comments: 12 pages, 1 figure, RevTeX Report-no: SPIN-1999/25, UG-1999/42 Journal-ref: Phys.Lett. B483 (2000) 271-276 \\ We study the thermodynamics of the confined and unconfined phases of superconformal Yang-Mills in finite volume and at large N using the AdS/CFT correspondence. We discuss the necessary conditions for a smooth phase crossover and obtain an N-dependent curve for the phase boundary. \\
