Understanding the relationship between the composition of a research team and the potential impact of their research papers is crucial as it can steer the development of new science policies for improving the research enterprise. Numerous studies assess how the characteristics and diversity of research teams can influence their performance across several dimensions: ethnicity, internationality, size, and others. In this paper, we explore the impact of diversity in terms of the authors' expertise. To this purpose, we retrieved 114K papers in the field of Computer Science and analysed how the diversity of research fields within a research team relates to the number of citations their papers received in the upcoming 5 years. The results show that two different metrics we defined, reflecting the diversity of expertise, are significantly associated with the number of citations. This suggests that, at least in Computer Science, diversity of expertise is key to scientific impact.

翻译：理解研究团队的构成与其研究论文潜在影响力之间的关系至关重要，因为这可以引导制定新的科学政策以改进研究事业。大量研究评估了研究团队的特征和多样性如何在不同维度（如民族、国际性、规模等）影响其绩效。本文探讨了作者专业多样性对影响力的作用。为此，我们检索了计算机科学领域的114K篇论文，分析了研究团队内研究领域的多样性与其论文在未来5年获得的引用次数之间的关系。结果表明，我们定义的两个反映专业多样性的指标与引用次数显著相关。这表明，至少在计算机科学领域，专业多样性是科学影响力的关键。
