Constraining unparticle-inspired model parameters using dwarf stars

Abstract

The unparticle-inspired model of gravity suggested by Georgi is based on that the standard model (SM) may contain a massive but scale invariant particles, which can be exchanged between SM massive particles, leading to a new force called ungravity. This would add a perturbed term to the Newtonian law of gravity at low energy. We use the minimum mass of hydrogen burning (MMHB) to constrain the relevant parameters of unparticle inspired model of gravity, on scales [Formula: see text] and [Formula: see text].
