通过标量-光子耦合的圈修正对标量暗物质与光子以外粒子相互作用的限制

Limits on scalar dark matter interactions with particles other than the photon via loop corrections to the scalar-photon coupling

V. V. Flambaum, I. B. Samsonov

AI总结:

针对质量超$10^{-3}$ eV的标量暗物质与非光子粒子相互作用信息不足的问题,研究通过计算标量-光子耦合的单圈量子修正,结合相关实验结果得到多类相互作用的新限制,部分限制强度提升2至15个数量级且排除了标量粒子解释μ子g-2反常的可能。

摘要:

对于质量超过$10^{-3}$ eV的标量粒子暗物质候选体,其与强子和轻子的相互作用强度信息有限,而它与光子的相互作用已得到充分研究。标量-光子耦合常数会受到包含标量-轻子、标量-夸克以及标量-W玻色子顶点的单圈费曼图带来的量子修正。我们计算了这些单圈量子修正,并通过重新利用测量标量-光子相互作用的实验结果,得到了标量粒子与电子、μ子、τ子、夸克、核子、胶子、希格斯粒子以及W玻色子相互作用的新限制。我们首次获得了重轻子和夸克相互作用的限制,且在特定质量区间内,其他相互作用的限制比以往文献中提出的强2到15个数量级,并排除了用标量粒子解释μ子$g-2$反常的可能性。

英文摘要:

There is limited information about the interaction strength of a scalar dark matter candidate with hadrons and leptons for a scalar particle mass exceeding $10^{-3}$ eV while its interaction with photon is well studied. The scalar-photon coupling constant receives quantum corrections from one-loop Feynman diagrams which involve the scalar-lepton, scalar-quark, and scalar-W boson vertices. We calculate these one-loop quantum corrections and find new limits on the scalar particle interactions with electron, muon, tau, quarks, nucleons, gluons, Higgs, and W bosons by re-purposing the results of experiments measuring the scalar-photon interaction. Limits on interactions of heavy leptons and quarks have been obtained for the first time, and limits on other interactions in certain mass intervals are 2 to 15 orders of magnitude stronger than those presented in previous publications and exclude the resolution of the muon $g-2$ anomaly with scalar particle.
