Abstract

One kind of walking technicolor (WTC) theories predict the existence of a new scalar particle called techni-dilaton (TD) which can explain the current Higgs data at the CERN Large Hadron Collider (LHC). We calculate the cross-sections for the production of the TD in association with single top quark (tϕj production) in the framework of the one-family model (1FM) at the LHC. Our numerical results show that their values are at the level of several tens fb over the mass range 100 GeV < M_ϕ < 600 GeV with the center-of-mass (c.m.) energy . We further analyze the signal induced by the tϕj production and the relevant Standard Model (SM) backgrounds.
