Nuclear interference versus dark sector excitation in the 248 keV LUX-ZEPLIN recoil candidate

Imtiaz Khan, Salvatore Capozziello, G. Mustafa +3

The 2026 LUX-ZEPLIN (LZ) high energy nuclear recoil search reports one event at $248\pm 23_{\mathrm{stat}}\pm 23_{\mathrm{sys}}\mathrm{keV}$ and finds the elastic isovector interaction $\math…
