Description
The search for Weakly Interacting Massive Particles (WIMPs) still holds many mysteries. Beyond the well-studied spin-independent (SI) interaction, the spin-dependent (SD) coupling is crucial for determining whether WIMPs can interact with the spin of nucleons.
Typically, SD interactions are searched for in the elastic-scattering region (0-25 keV). However, it is challenging to distinguish between SI and SD models because their energy spectra are very similar. A key point is that only the SD interaction can excite the nucleus of Xe-129, which can produce a unique inelastic-scattering signature.
In this talk, I will present our research on this inelastic-scattering signal, based on the dataset from the PandaX-4T experiment with a total exposure of 1.54 Tonne-Year.
