Abstract

Baryonic resonances, composed of three quarks, are excited states of the corresponding ground state particles. Modification of their properties, such as mass, width, and yield by the medium make them to be used to investigate the dynamics of the system formed in relativistic heavy ion collisions. Due to having very short lifetime (τ ~10-23s) these particles may (i) decay, (ii) rescatter, and (iii) regenerate between chemical and kinetic freeze-out temperatures of created medium in high energy collisions. Therefore, studying their characteristic properties provides information about quark gluon plasma (QGP), the new state of matter, and the following phase, hadronization, of the medium formed in collisions. Measurement of these resonances in different high energy collision systems allows explaining system size effect on resonance production mechanism. In this work, Δ (1232) ++ resonance, which is one of the baryonic resonances and excited state of proton, were studied with DPMJET-III event generator for proton lead (p-Pb) collisions at the energy of 5.02 TeV. In addition, derived values are compared with the experimental results and the effect of the medium formed in different relativistic collisions on the resonances is discussed.

Özet

Baryonik rezonanslar üç kuarktan oluşan uyarılmış durumlardır. Kütle, rezonans genişliği ve ürün bolluğu gibi karakteristik özellikleri ortam tarafından etkilenebilir, böylece bu parçacıkların ölçümleri ile rölativistik ağır iyon çarpışmaları sonucu oluşan sistemin dinamiği araştırılabilir. Çok kısa ortalama ömre(τ ~ 10-23s) sahip olan baryonik rezonanslar, yüksek enerjili çarpışmalarda oluşan ortamın kimyasal donma noktası ile kinetik donma noktası arasında (i) bozunabilir, (ii) yeniden saçılabilir ve (iii) yeniden üretilebilirler. Bu sebeple bu parçacıkların karakteristik özelliklerinin incelenmesi çarpışmalarda oluşan ve maddenin yeni hali olarak tanımlanan Kuark Gluon Plazma (KGP) ve onu takip eden hadronizasyon safhaları hakkında bilgi verebilir. Ayrıca bu rezonansların farklı yüksek enerjili çarpışma sistemlerinde incelenmesi oluşan ortam boyutlarının rezonans üretimi üzerine etkisini açıklayabilir. Bu çalışmada baryonik rezonanslardan biri ve protonun uyarılmış hali olan Δ(1232)++ rezonansları DPMJET-III olay üreticisi ile 5.02 TeV enerjili proton kurşun (p-Pb) çarpışmaları için incelenmiştir. Ayrıca elde edilen değerler deneysel sonuçlar ile karşılaştırılmıştır. Farklı rölativistik çarpışma sistemlerinde oluşan ortamın bu parçacık üzerine etkisi değerlendirilmiştir.
