Low energy electron (LEE) induced single strand break (SSB) has been studied for 2′-deoxycytidine-5′-monophosphate (5′-dCMPH) molecules in the gas phase by means of ab initio electronic structure methods and local complex potential based time-dependent wavepacket quantum mechanical calculations.

Production Mechanisms

AbstractIn light of the excess in the low-energy electron recoil events reported by XENON1T, many new physics scenarios have been proposed as a possible origin of the excess. One possible explanation is that the excess is a result of a fast moving dark matter (DM), with velocity $$v\sim $$ v ∼ 0.05–0.20 and mass between 1 MeV and 10 GeV, scattering off an electron. Assuming the fast moving DM-electron interaction is mediated by a vector particle, we derive collider constraints on the said DM-electron interaction. The bounds on DM-electron coupling is then used to constrain possible production mechanisms of the fast moving DM. We find that the preferred mass of the vector mediator is relatively light ($$\lesssim $$ ≲ 1 GeV) and the coupling of the vector to the electron is much smaller than the coupling to the fast moving DM.
