Exploring detection of nuclearites in a large liquid scintillator neutrino detector.

We take the JUNO experiment as an example to explore nuclearites in the future large liquid scintillator detector. Comparing to the previous calculations, the visible energy of nuclearites across the liquid scintillator will be reestimated for the liquid scintillator based detector. Then the JUNO sensitivities to the nuclearite flux are presented. It is found that the JUNO projected sensitivities can be better than 7.7×10-17 cm-2 s-1 sr-1 for the nuclearite mass 1015 GeV≤M≤1024 GeV and initial velocity 10-4≤β0≤10-1 with a 20 year running. Note that the JUNO will give the most stringent limits for downgoing nuclearites with 1.6×1013 GeV≤M≤4.0×1015 GeV and a typical galactic velocity β0=10-3. [ABSTRACT FROM AUTHOR]
