Phys. Rev. Lett. 83, 28–31 (1999)New Method for Detecting Charged Scalars at CollidersReceived 16 October 1998; revised 14 April 1999; published in the issue dated 5 July 1999 We propose a new method for detecting a charged (pseudo)scalar at colliders, based upon the observation that its Yukawa coupling to charm and bottom quarks can be large due to a significant mixing of the top and charm quarks. After analyzing the typical flavor mixing allowed by low energy data in the topcolor and the generic two-Higgs doublet models, we study the physics potential of the Tevatron, LHC, and linear colliders for probing such an s-channel charged resonance via the single-top (as well as W±h0) production. We show that studying its detection at colliders can also provide information on the dynamics of flavor-changing neutral current phenomena. © 1999 The American Physical Society URL:
