New production mechanisms for exotic quarks of superstring-inspired E6 models at ep colliders

Superstring-inspired E6 models often contain light (1 TeV) color-triplet states, h (spin zero) and h (spin 1/2), which may have sizable leptoquark couplings. We point out that the processes euh,hg and eghũ are possible new production mechanisms for supersymmetric particles at ep colliders which can rival the resonant production of scalar h leptoquarks via eq fusion and the standard production processes (e.g.,) for superparticles. We also briefly discuss the related reactions euh, qeh, and ughe.. AE
