Abstract

Bu çalışmada etkileşim Lagranjiyen yöntemi kullanılarak, dejenere durumdaki uyarılmış kuarkların Yüksek Işınlıklı Büyük Hadron Çarpıştırıcısında (YI-BHÇ) rezonans üretimleri incelenmiştir. YI-BHÇ’de rezonans da üretilen uyarılmış kuarkların iki-jet son durumuna sahip olduğu sinyal kanalı için hesaplamalar yapılmıştır. Uyarılmış kuark sinyalini ardalandan ayırt edecek sınırlandırmaları belirlemek için sinyal ardalan analizi yapılmıştır. Bu analiz vasıtasıyla belirlenen sınırlandırmalar kullanılarak YI-BHÇ’de uyarılmış kuarkın kütlesi için keşif, gözlem ve dışarlama limitleri hesaplanmıştır. Ayrıca uyarılmış kuark için kompozitlik ölçeği taraması yapılarak, farklı kütle değerleri için ulaşabileceği en üst kompozitlik ölçeği değerleri hesaplanmıştır. Son olarak 1’den küçük serbest parametre değerlerinde dahi uyarılmış kuarkın YI-BHÇ’de keşif edilebileceği gösterilmiştir. Tüm bu hesaplamaların sonucunda, YI-BHÇ’nin uyarılmış kuarkları araştırmada çok iyi bir potansiyele sahip olacağı ortaya çıkmıştır.

Resonance Production of the Excited Quark at High Luminosity Large Hadron Collider

Abstract

This study investigated the resonance production of excited quarks in the degenerate state using the interaction Lagrangian method. Calculations have been made for the signal channel in which the excited quarks produced in the resonance in High Luminosity Large Hadron Collider (HL-LHC) have dijet final states. Signal background analysis was performed to identify cuts to distinguish the excited quark signal from the background. Using the cuts determined by this analysis, the discovery, observation, and exclusion limits for the mass of the excited quark in the HL-LHC were calculated. In addition, a compositeness scale search was performed for the excited quark, and the highest compositeness scale values that it could reach for different mass values were calculated. Finally, it has been shown that the excited quark can be discovered in HL-LHC even with free parameter values less than 1. As a result of all these calculations, it has been revealed that HL-LHC will have an excellent potential in investigating excited quarks.
