 Title: Search for third-generation scalar leptoquarks in the t? channel in proton-proton collisions at ?s=8 TeV Authors: CMS CollaborationKarapınar, Güler Keywords: Compact Muon SolenoidLarge Hadron Collider (LHC)Leptons Issue Date: Jul-2015 Publisher: Springer Verlag Source: Khachatryan, V., Sirunyan, A.M., Tumasyan, A., Adam, W., Asilar, E., Bergauer, T.,...CMS Collaboration (2015). Search for third-generation scalar leptoquarks in the tτ channel in proton-proton collisions at √s=8 TeV. Journal of High Energy Physics, 2015(7). doi:10.1007/JHEP07(2015)042 Abstract: A search for pair production of third-generation scalar leptoquarks decaying to top quark and τ lepton pairs is presented using proton-proton collision data at a center-of-mass energy of s=8$$\sqrt{s}=8$$ TeV collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb−1. The search is performed using events that contain an electron or a muon, a hadronically decaying τ lepton, and two or more jets. The observations are found to be consistent with the standard model predictions. Assuming that all leptoquarks decay to a top quark and a τ lepton, the existence of pair produced, charge −1/3, third-generation leptoquarks up to a mass of 685 GeV is excluded at 95% confidence level. This result constitutes the first direct limit for leptoquarks decaying into a top quark and a τ lepton, and may also be applied directly to the pair production of bottom squarks decaying predominantly via the R-parity violating coupling λ333 ′. © 2015, The Author(s).
