Title: Resonances in positron-hydrogen scattering in dense quantum plasmas

We have investigated the S-wave resonance states in positron-hydrogen system embedded in dense quantum plasmas using Hylleraas-type wave functions within the framework of the stabilization method. The effect of quantum plasmas has been incorporated using the exponential-cosine-screened Coulomb (modified Yukawa-type) potential. Resonance parameters (both position and width) below the Ps nā€‰=ā€‰2 threshold are reported as functions of plasma screening parameters.
