Abstract

The non-zero masses of neutrinos are the first solidevidence beyond the Standard Model of particle physics. Seesawmechanism is one of the extensions to the Standard Model, which isgenerating Majorana type light neutrinos with corresponding heavyneutrino mass states. In this model, the smallness of the light neutrinomass (υμ < 1 eV) is explained by having heavy neutrino mass at theTeV scale that is an accessible regime at particle colliders. In thispaper, we describe a phenomenological study on heavy Majorananeutrino productions in proton-proton collisions at center-of-massenergies of 8 and 13 TeV. We consider that the heavy Majorananeutrino is produced by both dileptonic and trileptonic channels asproduction of a charged W boson. The cross section results of theheavy Majorana neutrinos for both same-sign and opposite-signevents in the dileptonic channel show a similar trend for the highermass region starting from 300 GeV/c2 when a pT > 5 GeV/c cutapplied on leptons. The results also show that the production of suchheavy mass neutrino particles is more likely to happen in thedileptonic channel than in the trileptonic channel.

Özet

Nötrinoların kütlelerinin sıfırdan farklı olması, parçacık fiziğindeki Standart Modelin ötesindeki ilk somut kanıttır. Seesaw mekanizması, ağır nötrino kütle durumlarına karşılık gelen Majorana tipi hafif nötrinolar üreten Standart Modelin uzantılarından biridir. Bu modelde, hafif nötrino kütlesinin (υ! < 1 eV) küçüklüğü, parçacık çarpıştırıcıları ile erişilebilir olan TeV ölçeğindeki ağır nötrino kütlesi ile açıklanmaktadır. Bu makalede, kütle merkezi enerjileri 8 ve 13 TeV olan proton-proton çarpışmalarındaki ağır Majorana nötrino üretimleri üzerine fenomenolojik bir çalışma sunulmaktadır. Ağır Majorana nötrinolarının yüklü W bosonlarının aracılığı ile üretilen hem iki-leptonik hem de üç- leptonik üretim kanalları dikkate alınmıştır.
