We compute the effective potential for scalar fields in asymptotically safe quantum gravity. A scaling and other functions generalize fixed point values of renormalizable couplings. The takes a non-polynomial form, approaching typically constant large fields. Spontaneous symmetry breaking may be induced by non-vanishing gauge strengthen arguments prediction ratio between masses top quark Higgs ...

A bstract Non-analyticity in co-moving momenta within the non-Gaussian bispectrum is a distinctive sign of on-shell particle production during inflation, presenting unique opportunity for “direct detection” particles with masses as large inflationary Hubble scale ( H ). However, strength such non-analyticity ordinarily drops exponentially by Boltzmann-like factor exceed . In this paper, we stud...

In this paper, we study a hybrid combination of Einstein–Hilbert action with curvature scalar R, and function f(R) in Palatini gravity within the context inflationary scenario, from Swampland conjecture point view. This model has been paid attention recent cosmological studies, its applications have widely studied literature. regard, using (using (C1) as first component dS swampland conjecture,...
