# Search for Third-Generation Scalar Leptoquarks in the t$Channel in Proton-Proton Collisions at$s$= 8 TeV The CMS Collaboration (2015) Search for Third-Generation Scalar Leptoquarks in the t$ Channel in Proton-Proton Collisions at $s$ = 8 TeV. Journal of High Energy Physics, 07, 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
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′.
