Abstract

In this study, the resonance productions of the sextet scalar diquarks are studied for the Future Circular Collider-based proton proton (FCC-pp) with 100 TeV centre of mass planned to build at the European Organization for Nuclear Research, CERN. For the scalar diquarks, decay width and cross sections are calculated as a function of the diquarks mass. Also, for the diquark signals and background, the kinematic cuts are applied on diquarks mass and statistical significant calculations are obtained. As a result, at the Future Circular Collider-based proton proton with 100 TeV centre of mass, for the scalar diquarks mass, discovery (5), observation (3) and exclusion (2) limit values are given. For these mass limit values are compared with mass limit values of the Large Hadron Collider (LHC) with 7 TeV centre of mass energy and the High Luminosity-Large Hadron Collider (HL-HLC) with 14 TeV centre of mass energy.

FCC PROTON-PROTON ÇARPIŞTIRICISINDA RENK ALTILI SKALER DİKUARKLARIN REZONANS ÜRETİMİ

Abstract

Bu çalışmada, Avrupa Nükleer Araştırma Merkezi’nde (CERN) kurulacak olan 100 TeV kütle merkezi enerjisine sahip geleceğin dairesel proton-proton tabanlı çarpıştırıcısında (FCC-pp), renk altılı skaler dikuarkların rezonans üretimi çalışılmıştır. Skaler dikuarklar için, dikuark kütlesine bağlı olarak bozunum genişliği ve tesir kesiti hesaplamaları yapılmıştır. Ayrıca dikuark sinyalini fondan ayırmak için kinematik kesmeleri uygulanıp istatistiksel önem hesaplamaları yapılmıştır. Sonuç olarak, 100 TeV kütle merkezi enerjili geleceğin dairesel proton-proton tabanlı çarpıştırıcısında (FCC-pp), skaler dikuarkların kütlesi için keşif (5), gözlem (3) ve dışarlama (2) limitleri verilmiştir. Bu kütle limit değerleri, 7 TeV kütle merkezi enerjisine sahip Büyük Hadron Çarpıştırıcısı (BHÇ) ve 14 TeV kütle merkezi enerjisine sahip Yüksek Işınlıklı Büyük Hadron Çarpıştırıcısından (YI-HLÇ) elde edilen değerler ile karşılaştırılmıştır.
