Abstract
The Littlest Higgs model with Tparity is providing an attractive solution to the finetuning problem This solution is only entirely natural if its intrinsic symmetry breaking scale f is relatively close to the electroweak scale We examine the constraints using the latest results from the 8 TeV run at the LHC Both direct searches and Higgs precision physics are taken into account The constraints from Higgs couplings are by now competing with electroweak precision tests and both combined exclude f up to 694 GeV or 560 GeV depending on the implementation of the downtype Yukawa sector Direct searches provide robust and complementary limits and constrain f to be larger than 638 GeV We show that the Littlest Higgs model parameter space is slowly driven into the TeV range Furthermore we develop a strategy on how to optimise present supersymmetry searches for the considered model with the goal to improve the constraints and yield more stringent limits on f This article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
