摘要

我们通过考虑中微子质量依赖于标量场的质量变化的中微子场景来研究物质密度如何影响中微子振荡。该标量场与高斯-博内（GB）不变量非最小耦合，导致其轮廓受到周围物质分布的隐式影响。利用来自太阳中微子实验的数据，我们推导了模型参数的约束条件，为在Gauss-Bonnet标量张量框架内变质量中微子的性质提供了新的见解。

Mass varying neutrino oscillation in scalar-Gauss-Bonnet gravity

We investigate how matter density affects neutrino oscillations by considering a mass-varying neutrino scenario where the neutrino mass depends on a scalar field. This scalar field is non-minimally coupled to the Gauss-Bonnet (GB) invariant, causing its profile to be implicitly influenced by the surrounding matter distribution. Using data from solar neutrino experiments, we derive constraints on the model parameters, providing new insights into the properties of mass-varying neutrino within the Gauss-Bonnet scalar-tensor framework.
