CERN'deki Büyük Hadron Çarpıştırıcısı'ndaki (BHÇ) deneylerden toplanan verilerle süpersimetri izi aranmaktadır. Araştırmalardan bazıları renkli süpersimetrik parçacıklara odaklanırken, bazıları ise chargino-nötralino veya sleptonların elektrozayıf üretimine odaklanmışlardır. Şu ana kadar yapılan deneysel araştırmalarda süpersimetrik parçacık izine rastlanılmadığından, bu parçacıkların kütleleri üzerine sınırlamalar getirilmiştir. Bu fenomenolojik çalışmada, 33 TeV’lik Kütle Merkezi (K.M.) enerjisinde proton-proton çarpıştırıcısında slepton sinyali incelenmiş ve 100 fb-1 ışıklılığa karşılık gelen verilerle, en hafif süpersimetrik parçacık ile slepton arasındaki kütle farkının çok küçük olduğu durumda (ΔM = 5 GeV), 270 GeV'ye kadar kütleye sahip slepton sinyalinin keşfedilebileceği gösterilmiştir.

Probing Compressed Slepton Production at Future Large Hadron Collider
Various supersymmetry searches are carried out at the Large Hadron Collider (LHC) at CERN. While some searches have focused on the color sector, others focused on electroweak production of charginos-neutralinos and sleptons. Since no sign of supersymmetry has yet to be found, limits are set on the masses of the supersymmetric particles. In this phenomenological study, we probe direct slepton signal production in compressed mass spectra scenario at the potential future proton-proton collider operating at a center of mass energy of 33 TeV. We show that slepton signal with masses up to 270 GeV can be discovered at the future hadron collider with the data corresponding to 100 fb-1 integrated luminosity when ΔM =5 GeV.
