Cosmic variation of proton-to-electron mass ratio with an interacting Higgs scalar field

Abstract: We discuss that it is quite possible to realize the smooth transition of the universe between a matter/radiation dominated deceleration and a dark energy dominated acceleration, even with a variation of proton-to-electron mass ratio μ. The variation is incorporated into the theory of gravity using a cosmological Higgs scalar field with a non-trivial self-interaction potential, leading to a varying Higgs vacuum expectation value (VEV). This matches well with the data from molecular absorption spectra of a serie… Show more

“…This is, however, not necessarily true given the fact that one may perfectly entertain the possibility that the vacuum expectation value (VEV) of the Higgs doublet in the EW theory is also affected by cosmic drift, see e.g. [40][41][42][43] Thus the two contributions ∆mp mp and ∆me me could actually be comparable. On the other hand, if the Higgs VEV can be time dependent this makes the entire spectrum of fundamental particle masses (fermions, gauge bosons and Higgs scalar) in the SM subject to potential cosmic time evolution!…”

“…There is always a possibility that further extensions of the theory can turn out to be a rejuvenation [25][26][27][28][29][30]. Recent works in this regard show that an interacting Higgs scalar field in a generalized Brans-Dicke theory can act as the driver of cosmological expansion [31] and at the same time explain the cosmic variation of Higgs vacuum expectation value [32,33].…”
