标题： Nonminimally-coupled warm Higgs inflation: Metric vs. Palatini Formulations

摘要： 在本工作中，我们在度规和Palatini方法的背景下研究了非最小耦合希格斯模型的温暖膨胀情景。我们特别考虑了一个形式为$\Gamma=C_{T}T$的耗散参数，其中$C_{T}$是一个耦合参数，并且仅关注标量场与辐射流体之间的强相互作用 regime。我们计算了所有相关的宇宙学参数，并使用观测的Planck 2018数据对模型进行限制。我们发现$n_s$和$r$的值与观测界限一致。利用观测数据，我们约束了非最小耦合的温暖希格斯膨胀在度规和Palatini情况下的$\xi$和$\lambda$之间的关系。 为了使$n_s$和$r$与观测结果一致，我们发现它们的值比通常（冷）非最小耦合希格斯膨胀的值高两个数量级。 显示英文摘要

摘要： In this work, we study the non-minimally-coupled Higgs model in the context of warm inflation scenario on both metric and Palatini approaches. We particularly consider a dissipation parameter of the form $\Gamma=C_{T}T$ with $C_{T}$ being a coupling parameter and focus only on the strong regime of the interaction between inflaton and radiation fluid. We compute all relevant cosmological parameters and constrain the models using the observational Planck 2018 data. We discover that the $n_s$ and $r$ values are consistent with the observational bounds. Having used the observational data, we constrain a relation between $\xi$ and $\lambda$ for the non-minimally-coupled warm Higgs inflation in both metric and Palatini cases. To produce $n_s$ and $r$ in agreement with observation, we find that their values are two orders of magnitude higher than those of the usual (cold) non-minimally-coupled Higgs inflation.
