Single Production of Charged Top-Pions at High Energy Linear e^＋e^- Colliders
摘要
The dominant decay modes of charged top-pions (πt^± ) are t-↑b or -↑tb. We consider the single production of charged top-pions in association with a top quark via e^+e^- annihilation and calculate the production cross section of the processes e^+e^- → -↑tbπ^+ (t-↑bπ^-) at the leading order. We find that it can reach 1.2 fb with reasonable parameter values.The charged top-pions may be detected via the channel tbπ^± in the future high energy e^+e^- colliders.
