Abstract: We investigate the potential for discovering new physics through the low-energy scattering processes e − p → e − (µ − )Λc, which could be accessible in the forthcoming ep scattering experiments once adapted to our proposed setups. In the framework of low-energy effective Lagrangian, we demonstrate that, compared with the conventional flavor-changing-neutral-current weak decays of charmed hadrons and the dilepton productions at high-energy colliders, the low-energy scattering processes can provide more competit… Show more

“…where L SM eff and L LQ eff represent the SM and the LQ contribution, respectively. Since the SM long-distance effects do not contribute to the scattering processes [82], while the short-distance effects are strongly GIM suppressed [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75], here we can safely neglect the contribution from L SM eff . The most general low-energy effective Lagrangian L LQ eff induced by tree-level exchanges of LQs is given by [53]…”
