[ABSTRAK
Dalam fotoproduksi kaon, banyak data eksperimen yang telah didapatkan namunmasih sedikit teori yang dapat menjelaskan hasil tersebut dengan baik. Denganmeneliti peran resonans hyperon dalam fotoproduksi kaon, diharapkan dapatmemahami reaksi ini dengan lebih baik. Penelitian ini menggunakan metodeLagrangian efektif dengan interaksi yang lebih konsisten untuk mencari nilaiamplitudo hamburan, kemudian parameter yang tidak diketahui dalam amplitudohamburan dicocokkan dengan data eksperimen dengan meminimalisasikan nilai2=N. Data eksperimen yang digunakan ialah penampang lintang dan observabelpolarisasi. Hasil yang didapatkan menunjukkan nilai yang lebih sesuai dengan dataeksperimen, terutama pada daerah sudut mundur.ABSTRACT
Kaon photoproduction has been investigated and experimented but still few theoriescan explain it well. Investigating hyperon resonance in kaon photoproduction mayprovide a better explanation about this process. This study was conducted by usingan effective Langrangian method with consistent interaction to calculate scatteringamplitude, then the unknown parameters in scattering amplitude would be fittedwith experimental data by minimizing 2=N value. Experimental data which isused are cross-section and polarization observable. The results showed values moreprecise with the experimental data, especially at backward angle., Kaon photoproduction has been investigated and experimented but still few theoriescan explain it well.
