The Jiangmen Underground Neutrino Observ.tory(JUNO)is a large liquid scintillator detector designed to explore many topics in fundamental *** this study,the potential of searching for proton decay in the p→νK^(+)mode with JUNO is *** kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for ***,the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed *** on these adv.ntages,the detection efficiency for the proton decay v.a p→νK^(+)is 36.9%±4.9%with a background lev.l of 0.2±0.05(syst)±0.2(stat)ev.nts after 10 years of data *** estimated sensitiv.ty based on 200 kton-years of exposure is 9.6×1033 years,which is competitiv. with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies.
