我们研究了超轻暗物质（ULDM）与标准模型粒子之间的相互作用对ULDM有效自相互作用耦合常数的影响。分析表明，单圈量子修正会导致有效耦合常数大幅增加，而这受到宇宙学观测的严格限制。研究结果凸显了在ULDM探测中考虑量子修正的重要性。
英文摘要
We investigate the implications of interactions between ultralight dark matter (ULDM) and Standard Model fermions for the radiative stability of the ULDM potential. By matching the heavy fermion onto a low-energy scalar effective field theory, we derive the one-loop threshold corrections to the ULDM mass and self-interaction couplings. We interpret these corrections in terms of radiative naturalness conditions. For the parameter region motivated by cosmological and galactic considerations, the quadratic correction provides the strongest naturalness criterion, while the direct and cubic-induced quartic corrections remain subdominant. Our results illustrate how radiative effects can constrain the parameter space satisfying our radiative-naturalness criterion based on threshold corrections.
