Son yıllarda yapılan yüksek enerji
fiziği deneylerinde Standart Model çerçevesinde bilinen parçacık yapıları
dışında yeni parçacıklar dedekte edilmiştir. Bu gelişmeler, Standart Model
ötesi fizik açısından oldukça önemlidir. İç yapısı nedeniyle egzotik parçacık
diye adlandırılan bu parçacıkların hem deneysel, hemde teorik çalışmalara
farklı bir yön vereceği düşünülmektedir. Bu parçacıklar bugüne kadar tam olarak
açıklanamayan madde-antimadde asimetrisi, evrenin oluşumu, karanlık madde,
karanlık enerji, nötron yıldızlarının iç yapısı gibi pekçok konu hakkında
ipuçları verebilir. Ayrıca bu parçacıkların keşfi son yıllarda hadron
spektroskopisine olan ilgiyi oldukça artırmıştır. Bu çalışmada, bugüne kadar
tespit edilen egzotik parçacıkların kütle, kuantum sayıları, bozunma
genişlikleri gibi temel özellikleri hakkında bilgi sunulacaktır.

Exotic Hadrons

In recent years, in the high energy
physics experiments, new particles have been detected except for known particle
structures in the Standard Model framework. These developments are also very
important in terms of physics beyond the Standard Model. It is thought that
particles in this different structure, which is called exotic particle due to
internal structure, will give a different direction to both experimental and
theoretical studies. These particles can give clues on the asymmetry of
matter-antimatter, the formation of the universe, the dark matter, the dark
energy, the inner structure of neutron stars, and so forth. Moreover, the
discovery of these particles has widely increased the interest in hadron
spectroscopy in recent years. In this work, information on the basic properties
of exotic particles, such as mass, quantum numbers, and decay widths, which are
detected until now, will be presented.
