标题： Dark Forces at DA$Φ$NE

摘要： DA$\Phi$NE $\Phi$-工厂是寻找标准模型之外的力的理想场所。 通过使用KLOE探测器，通过对$\Phi$ Dalitz衰变、U$\gamma$事例和Higgsstrahlung过程的研究，设定了U玻色子耦合$\varepsilon^2$的数量级为$10^{-5} \div 10^{-7}$以及$\alpha_{\rm D} \times \varepsilon^2$乘积的限制。 这些限制的改进得益于KLOE探测器和KLOE-2的DA$\Phi$NE升级。 显示英文摘要

摘要： The DA$\Phi$NE $\Phi$-factory is an ideal place to search for forces beyond the Standard Model. By using the KLOE detector, limits on U-boson coupling $\varepsilon^2$ of the order of $10^{-5} \div 10^{-7}$ and on the $\alpha_{\rm D} \times \varepsilon^2$ product have been set through the study of the $\Phi$ Dalitz decay, U$\gamma$ events and the Higgsstrahlung process. An improvement of these limits is expected thanks to the KLOE detector and DA$\Phi$NE upgrades of KLOE-2.
