近日，英国牛津大学Christopher Couzens团队研究了罗马超重力的局域化。2025年9月11日出版的《高能物理杂志》发表了这项成果。

研究组导出了六维欧几里得罗马超重力等变局域作用的一般公式。他们的结果不需要解决任何运动方程，而是在假设存在超对称解的情况下得到的。研究组证明了上壳作用完全由r对称杀伤向量和拓扑数据决定。研究组很容易恢复文献中已知的结果，对迄今为止未知的解决方案进行预测，并与全息场论对偶相匹配。

Abstract: We derive a general formula for the on-shell action of six-dimensional Euclidean Romans supergravity using equivariant localization. Our results are obtained without the need for solving any of the equations of motion, instead working on the assumption of the existence of a supersymmetric solution. We show that the on-shell action is completely determined in terms of the R-symmetry Killing vector and topological data. We easily recover known results in the literature, make predictions for hitherto unknown solutions, and also match to holographic field theory duals.
