Title: Production of hht and htT in the littlest Higgs model with T parity

Abstract

In the littlest Higgs model with T parity, which predicts a pair of T-even and T-odd partners for the top quark, the top-quark interactions are altered with respect to the standard model predictions and the deviation will manifest in various top-quark processes. In this work we examine the effects in htt productions at the International Linear Collider and CERN LHC. We find that, in the allowed parameter space, the cross sections can be significantly deviated from the standard model predictions and thus provide a good test for the littlest Higgs model with T parity. We also examine the new production channel, htT or hTt production, at the LHC, which gives the same final states as htt production due to the dominant decay T{yields}Wb. We find that, compared with htt production, this new production channel can have a sizable production rate for a T quark below the TeV scale. Such a production will be counted into htt events or possibly extracted from htt events, depending on if we can distinguish the T quark from the top quark from mass reconstructions.
