We present a simple toy model of cosmic acceleration driven purely by a self-interacting scalar field embedded in theory of grand unification. The scalar self-interaction is Higgs-like and provokes a spontaneous symmetry breaking. The coefficient of the quadratic term in the self-interaction potential has an evolution and it leads to a cosmic varia...

... using Eq. (3), we calculate the change in proton-toelectron mass ratio μ μ and plot it in Fig. 3, alongwith the data-points from Quasar absorption spectra as in Table 1. It shows a satisfactory fit in between theory and observations. ...
