Higgs inflation with the Holst and the Nieh–Yan term

The action of loop quantum gravity includes the Holst term and/or the Nieh–Yan term in addition to the Ricci scalar. These terms are expected to couple nonminimally to the Higgs. Thus the Holst and Nieh–Yan terms contribute to the classical equations of motion, and they can have a significant impact...
