摘要：
RES-NOVA项目是一项实验计划，旨在利用PbWO$_{4}$低温探测器，在低本底环境中于低温下运行，探测下一次银河系超新星中微子。通过使用考古铅（Pb）作为靶材料，RES-NOVA利用其高放射性纯度、大核质量以及$^{207}$Pb的天然丰度，使其非常适合通过核散射探索自旋无关和自旋相关的暗物质（DM）相互作用。本工作为RES-NOVA技术演示器开发了一个本底模型，并评估了其对暗物质探测的意义。核矩阵元素的详细计算，结合考古铅的独特性质，证明了RES-NOVA作为现有直接探测实验的补充工具，用于研究暗物质相互作用的潜力。该实验将在跨越4个数量级的广泛质量范围内（从亚GeV/$c^2$到TeV/$c^2$）进行暗物质搜索。在最乐观的情况下，RES-NOVA预计可探测到质量分别为2 GeV/$c^2$和20 GeV/$c^2$的候选粒子的暗物质-核子截面低至1$\ imes 10^{-43}$ cm$^2$和2$\ imes 10^{-46}$ cm$^2$。
英文摘要：
The RES-NOVA project is an experimental initiative aimed at detecting neutrinos from the next galactic supernova using PbWO$_{4}$ cryogenic detectors, operated at low temperatures in a low-background environment. By utilizing archaeological lead (Pb) as the target material, RES-NOVA leverages its high radiopurity, large nuclear mass, and the natural abundance of $^{207}$Pb, making it well-suited for exploring both spin-independent and spin-dependent Dark Matter (DM) interactions via nuclear scattering. This work presents a background model developed for the RES-NOVA technology demonstrator and evaluates its implications for Dark Matter detection. Detailed calculations of nuclear matrix elements, combined with the unique properties of archaeological Pb, demonstrate RES-NOVA's potential as a complementary tool to existing direct detection experiments for studying Dark Matter interactions. The experiment will conduct DM searches over a broad mass range spanning 4 orders of magnitude, from sub-GeV/$c^2$ to TeV/$c^2$. In the most optimistic scenario, RES-NOVA is expected to probe DM-nucleon cross-sections down to 1$\times 10^{-43}$ cm$^2$ and 2$\times 10^{-46}$ cm$^2$ for candidates with masses of 2 GeV/$c^2$ and 20 GeV/$c^2$, respectively.
