Abstract

INDONESIA:

Neutrino merupakan fermion dengan spin setengah dan tidak bermuatan. Neutrino menarik diteliti karena hingga saat ini eksperimen dari proses osilasi flavor neutrino belum terdeteksi. Oleh karena itu, probabilitas perubahan flavor neutrino electron dari sumber yaitu matahari diperhitungkan sampai mendapatkan persamaan probabilitas perubahan flavor neutrino dengan tepat. Pada penelitian ini mengkaji tentang perubahan flavor neutrino elektron menjadi flavor neutrino yang lain dengan mencari probabilitas perubahan flavornya melalui pendekatan teori medan kuantum: kuantisasi I dan kuantisasi II. Hasilnya, pada kuantisasi I probabilitas osilasi flavor neutrino dari neutrino aktif ke neutrino steril, neutrino steril ke neutrino steril, dan neutrino aktif ke neutrino aktif dengan adanya interferensi antara energi positif dan energi negatif neutrino, sedangkan pada kuantisasi II, probabilitas osilasi flavor neutrino tidak melibatkan proses interferensi energi positif dan energi negatif sehingga pada kuantisasi kedua terdapat probabilitas perubahan flavor neutrino untuk energi positif dan untuk energi negatif.

ENGLISH:

Neutrino is Fermion fundamental particle having a half spin and uncharged. Neutrino is interesting to be researched in order to this experiment of neutrino flavor conversion has not been found up to. Furthermore, the conversion probability of electron neutrino from a source that is the sun is counted until gotten the neutrino flavor conversion probability exactly. In this research, it discusses about electron neutrino flavor conversion to become other flavor neutrino by searching flavor conversion probability by quantum field theory approached: first and second quantization.The result at the first quantization electron neutrino oscillation probability from the active neutrino to the sterile neutrino, the sterile neutrino to the sterile neutrino, and the sterile neutrino to the active neutrinoby there is an interference between neutrino positive energy and negative energy, whereas at the second quantization, neutrino flavor oscillation probability do not presence the interference process of positive energy and negative energy so at the second quantization there is the neutrino flavor conversion probability to positive energy and negative energy.
