21. Thus, antineutrino detectors are being studied to locate and monitor them at a distance. 22. The 3 ?3 diagonal blocks describe neutrino neutrino and antineutrino antineutrino mixing, respectively. 23. The total geoneutrino flux is the sum of contributions from all antineutrino -producing radionuclides. 24. "Ordinary " double beta decay results in the emission of two electrons and two antineutrinos . 25. For example, CP transforms a left-handed neutrino into a right-handed antineutrino . 26. This releases additional energy in the form of beta particles, antineutrinos , and gamma rays. 27. The question, thus, remains : can neutrinos and antineutrinos be differentiated only by chirality? 28. For neutrino antineutrino pairs, " a " and " c " represent neutrino and antineutrino. 29. For neutrino antineutrino pairs, " a " and " c " represent neutrino and antineutrino . 30. Of 841 candidate antineutrino events, 106 were identified as geoneutrinos using unbinned maximum likelihood analysis.
