Description
XENONnT is a dark matter direct detection experiment, utilizing 5.9 t of instrumented liquid xenon, located at the INFN Laboratori Nazionali del Gran Sasso. In this work, we predict the experimental background and project the sensitivity of XENONnT to the detection of weakly interacting massive particles (WIMPs). The expected average differential background rate in the energy region of interest, corresponding to (1, 13) keV and (4, 50) keV for electronic and nuclear recoils, amounts to 12.3±0.6 (keV ty)-1 and (2.2±0.5)× 10− 3 (keV ty)-1, respectively, in a 4 t fiducial mass. We compute unified confidence intervals using the profile construction method, in order to ensure proper coverage. With the exposure goal of 20 ty, the expected sensitivity to spin-independent WIMP-nucleon interactions reaches a cross-section of 1.4× 10− 48 cm 2 for a 50 GeV/c 2 mass WIMP at 90% confidence level, more than one order of …
