Abstract
In this work we numerically re-examine the loop-induced WIMP-nucleon scattering cross section for the simplified dark matter models and the constraint set by the latest direct detection experiment. We consider a fermion, scalar or vector dark matter component from five simplified models with leptophobic spin-0 mediators coupled only to Standard Model quarks and dark matter particles. The tree-level WIMP-nucleon cross sections in these models are all momentum-suppressed. We calculate the non-suppressed spin-independent WIMP-nucleon cross sections from loop diagrams and investigate the constrained space of dark matter mass and mediator mass by Xenon1T. The constraints from indirect detection and collider search are also discussed.
Highlights
In this work we numerically re-examine the loop-induced weakly interacting massive particle (WIMP)-nucleon scattering cross section for the simplified dark matter models and the constraint set by the latest direct detection experiment
According to the different interacting methods between WIMP and ordinary matter, the WIMP search experiments are divided into three classes: direct detection (DD), indirect detection (ID) and collider search
We numerically re-examine the loop-level SI cross section for the so-called simplified dark matter models and the constraint set by the latest direct detection experiments [8, 9]
Summary
In this work we numerically re-examine the loop-induced WIMP-nucleon scattering cross section for the simplified dark matter models and the constraint set by the latest direct detection experiment. There has been no well-established observation of dark matter from direct detection experiments, leading instead to upper limits on the WIMP-nuclei scattering cross section.
