论文摘要
分析了五维的Tachyon-Chern-Chern-Chern-Simons作用及其与单巴里族状态的相关性，在用于抗反应风味的全息QCD的V-QCD模型的背景下。 Tachyon-Chern-Simons 5形式的最通用形式，与对称性和风味异常兼容。它是非平凡的量规5维形式的总和，也是一种不变的封闭5形式，可再现风味异常。重力理论的单巴里元解决方案是由DBI和Tachyon-Chern-Chern-Simons作用引起的。重子被意识到是散装轴向静态。 Baryon Ansatz和场方程是得出的，并确定边界条件，这确保溶液具有有限的边界能量和单位Baryon电荷。边界巴里数是根据tachyon-chern-simons动作的通用（封闭）部分计算得出的，该数字与散装轴向激数数字相吻合。
The structure of the five-dimensional Tachyon-Chern-Simons action and its relevance to single-baryon states in the context of the V-QCD models for holographic QCD with backreacting flavor are analyzed. The most general form of the Tachyon-Chern-Simons 5-form, compatible with symmetries and flavor anomalies is determined. It is the sum of a non-trivial gauge-invariant 5-dimensional form and a non-invariant closed 5-form that reproduces the flavor anomalies. Single-baryon solutions of the gravity theory, arising from the DBI plus Tachyon-Chern-Simons actions are considered. The baryon is realised as a bulk axial instanton. The baryon ansatz and the field equations are derived and the boundary conditions are determined, which ensure that the solution has finite boundary energy and unit baryon charge. The boundary baryon number, which is computed from the universal (closed) part of the Tachyon-Chern-Simons action, is shown to coincide with the bulk axial instanton number.
