Narrow Results

We have studied a top-Higgs production process in the topcolor assisted technicolor (TC2) model. The studies show that the production cross-section of is at the order of magnitude 10 fb in reasonable parameters space of TC2 model. A few hundred events of top-Higgs can be produced each year at the high energy linear e⁺e^- colliders (LC). The top-Higgs may be directly observed via this process.

The top pions are the typical particles predicted by the top-color-assisted technicolor (TC2) model, and the observation of these particles can be regarded as the direct evidence of the TC2 model. In this paper, we study the charged and neutral top pion production process . The results show that the production rates can reach the level of tens of fb with reasonable parameter values. So one can expect that enough signals could be produced in the International Linear Collider (ILC) experiments. Furthermore, the flavor-changing (FC) decay mode is the best channel for detecting the neutral top pion, due to the clean SM background. With a large number of events and the clean background, the neutral top pion should be observable in future ILC experiments.
