我们开发了一个用于计算奇异自旋-1介子热谱函数的通用全息框架。体普罗卡质量编码了内插算符的规范紫外维度，使得在零空间动量极限下，具有不同紫外标度的通道能够在统一的膜流形式中得到处理。我们在具有胶子凝聚背景的软壁模型中，对混合π₁和类四夸克Zc通道测试了这个框架。结果表明，两个通道的解离温度都低于相变温度。增加c会延迟两个通道的解离，但通过不同的效应：在π₁通道中，真空质量位移和热谱变形都起作用，而在Zc通道中后者占主导。然而，在相同环境下，Zc共振比π₁共振在更低温度下解离。
英文摘要
We develop a general holographic framework for computing thermal spectral functions of exotic spin--1 mesons. A bulk Proca mass encodes the canonical ultraviolet dimension of the interpolating operator, allowing channels with different ultraviolet scaling to be treated within a unified membrane-flow formalism in the zero-spatial-momentum limit. We test this framework in a soft-wall model with a gluon-condensate background for the hybrid $π_1$ and tetraquark-like $Z_c$ channels. The results show that dissociation temperatures of both channels lie below the phase transition temperatures. Increasing $c$ delays dissociation in both channels, but through different effects: both the vacuum-mass shift and thermal spectral deformation contribute in the $π_1$ channel, whereas the latter dominates in the $Z_c$ channel. Nevertheless, for the same environment, the $Z_c$ resonance dissociates at a lower temperature than the $π_1$ resonance.
