Yüksek Işınlıklı Büyük Hadron Çarpıştırıcısı Bazlı Müon-Proton Çarpıştırıcılarında Uyarılmış Müon Üretimi

Öz

Bu çalışmada müon+foton son durumuna sahip spin-1/2 uyarılmış müonun Yüksek Işınlıklı Büyük Hadron Çarpıştırıcısı (YI-BHÇ) bazlı müon-proton çarpıştırıcısında üretimi incelenmiştir. Kütle merkezi enerjisi 9,16 TeV ve yıllık ışınlık değeri 15 fb-1 olan μp çarpıştırıcısında, uyarılmış müonların kontak etkileşim yöntemiyle üretilip ayar etkileşimi yöntemiyle fotonlu kanala bozunumu araştırılmıştır. Uyarılmış müon sinyalini ardalandan ayırmak için sinyal-ardalan analizi yapılmıştır. Bu analiz sonucunda belirlenen keşif sınırlamaları uygulanarak YI-BHÇ bazlı müon-proton çarpıştırıcısında uyarılmış müonun kütlesi için keşif, gözlem ve dışarlama limitleri tespit edilmiştir. Bu sonuçlara göre kompozitlik skalasının Λ = m_(μ^* ) değeri için uyarılmış müonlar 6570 GeV’e kadar bu çarpıştırıcıda keşfedilebilecektir.

Excited Muon Production at High Luminosity Large Hadron Collider-Based Muon-Proton Colliders

Öz

In this study, we investigated the production of spin-1/2 excited muons with a muon+photon final state at a High Luminosity Large Hadron Collider (HL-LHC) - based muon - proton collider. In the μp collider, which has a center of mass energy of 9.16 TeV and an annual luminosity of 15 fb-1, the production of excited muons by the contact interaction method and their decay into the photon channel by the gauge interaction method were investigated. Signal–background analysis was performed to separate the excited muon signals from the background. By applying the discovery cuts determined as a result of this analysis, the discovery, observation, and exclusion limits for the mass of the excited muon in the HL-LHC-based muon-proton collider were determined. According to these results, for Λ = m_(μ^* ), excited muons can be discovered up to 6570 GeV at this collider.
