$R^2\log R$ quantum corrections and the inflationary observables

Ido Ben-Dayan, Shenglin Jing, Mahdi Torabian +2

We study a model of inflation with terms quadratic and logarithmic in the Ricci scalar, where the gravitational action is $f(R)=R+\alpha R^2+\beta R^2\ln R$. These terms are expected to aris…
