Probing Scalar-Neutrino and Scalar-Dark-Matter Interactions with PandaX-4T
Author(s): Tao Li et al. (PandaX Collaboration)
Scalar-mediated interactions may exist among neutrinos, dark matter particles, or between the two. Double $β$-decay experiments provide a powerful tool to probe such exotic interactions. Using $^{136}\mathrm{Xe}$ double $β$-decay data from PandaX-4T, we perform the first direct spectral search in th… [Phys. Rev. Lett. 136, 241802] Published Wed Jun 17, 2026
