Abstract
Hadron fiziğinin teorisi kuantum renk dinamiğidir. Kuantum renk dinamiğinde güçlü çiftlenim sabiti orta ve düşük enerji bölgesinde neredeyse sonsuza gitmektedir. Bu nedenle kuarklar hadronlar içerisinde hapsolmuşlardır. Kuark hapsinin gerçekleştiği enerji bölgesinde pertürbasyon teorisi kullanılamaz bundan dolayı pertürbatif olmayan yöntemlere ihtiyaç vardır. Kiral pertürbasyon teorisi bu yöntemlerin en güçlülerinden biridir. Bu çalışmada üniter kiral pertürbasyon teorisinde üç mezon durumu araştırıldı. πD^* ¯D^* üç parçacık molekül durumunu Faddeev Denklemini sabit merkez yaklaşıklığı yöntemini kullanarak çözdüldü. İki parçacık D^* ¯D^*durumunu küme olarak alındı ve üçüncü parçacık olan π (pion) bu kümeden saçtırıldı. Yaptığımız hesapların sonucunda izospin Ι=1 olan, kütlesi 4156 MeV ve genişliği yaklaşık 130 MeV olan yarı bağlı durum elde edildi.
