Single Sbottom/Scharm Production at HERA in an R-Parity Breaking Supersymmetric Model

Abstract

We investigate the production process of the single scalar bottom quark (sbottom) and scalar charm quark (scharm) at HERA. The sbottom and scharm could be produced via an R-parity breaking interactions ${\lambda }_{123}^{\prime }\ne 0$ in the Minimal Supersymmetric Standard Model (MSSM). These processes give a slight excess in the invariant mass $M_{eq}$ distribution of the high $Q^2$ deep inelastic scattering for sufficiently heavy gauginos and the scalar top (stop). For the light gauginos and stop, it is shown that the tagging of $b/c$-quarks and charged leptons with high transverse energies will be indispensable to search for the processes.
