WallGo investigates: Theoretical uncertainties in the bubble wall velocity

This record contains the datasets accompanying the publication“Theoretical uncertainties in the bubble wall velocity” (WallGo Collaboration). The data were generated using the WallGo software framework and are used to quantify theoretical uncertainties in state-of-the-art calculations of the bubble wall velocity during first-order cosmological phase transitions. They include numerical results for two extensions of the Standard Mode (SM), the inert doublet model (IDM) and the singlet exteded SM, covering variations in: • the set of particles taken out of equilibrium, • logarithmically and power-enhanced collision integrals, • thermal mass treatments, • nucleation temperatures, • parametrizations of the bubble wall profile (tanh ansatz), and • the perturbative order of the effective potential. Together, these datasets enable the detailed uncertainty budget presented in the associated publication and provide reference results for benchmarking wall velocity and gravitational wave predictions. Whenever applicable, the data files are organized by figure number, model, parameter point, and source of uncertainty e.g. `Fig2Right_IDM_BM1_OutOfEq`.The metadata in the respective files describes the simulation setup, input parameters, and the version of WallGo used for each dataset.本数据集配套发表于论文《泡壁速度中的理论不确定性》（*Theoretical uncertainties in the bubble wall velocity*），由WallGo合作组（WallGo Collaboration）发布。 本数据集依托WallGo软件框架生成，旨在量化一级宇宙学相变过程中泡壁速度的前沿计算所涉及的理论不确定性。 数据集包含标准模型（Standard Model, SM）的两类扩展模型的数值计算结果，分别为惰性双态模型（Inert Doublet Model, IDM）与单态扩展标准模型（Singlet Extended SM），覆盖以下变量维度： - 脱离平衡态的粒子集合 - 对数与幂次增强的碰撞积分项 - 热质量处理方案 - 成核温度 - 泡壁轮廓的参数化形式（双曲正切假设，tanh ansatz） - 有效势的微扰阶数 上述整套数据集可支撑配套论文中详细的不确定性量化分析，并为泡壁速度与引力波预言的基准测试提供参考结果。 在适用场景下，数据文件按图号、模型、参数点与不确定性来源进行组织，例如命名格式为`Fig2Right_IDM_BM1_OutOfEq`。各文件中的元数据会说明对应数据集的模拟设置、输入参数以及所使用的WallGo软件版本。
