@article{Joshipura2020InflationAL, title={Inflation and long-range force from a clockwork D term}, author={Anjan S. Joshipura and Subhendra Mohanty and K. Patel}, journal={Physical Review D}, year={2020}, volume={103}, pages={035008} }

Cosmic inflation driven by the vacuum energy associated with the $D$ term of a supersymmetric Abelian gauge group and a possible existence of long-range force mediated by an ultralight gauge boson ${Z}^{\ensuremath{'}}$ are two extreme examples of models based on extra $U(1)$ symmetries. Large vacuum energy sets the scale of inflation while the scales of long-range forces induced by anomaly free extra gauged $U(1)$ symmetries are constrained by neutrino oscillations, binary pulsar timings, and…
