Upper Bounds on the Mass of Fundamental Fields from the Primordial Universe

We study the fluctuations in the vacuum zero-point energy associated with quantum fields and their statistical distributions during inflation. It is shown that the perturbations in the vacuum zero-point energy have large amplitudes that are highly non-Gaussian. The effects of vacuum zero-point fluct...
