We show that the existence of the cosmological constant can be connected to a nonminimal derivative coupling, in the action of gravity, between the geometry and the kinetic part of a given scalar field without introducing any effective potential of scalar fields. Exact solutions are given.

  1. Inflation with nondynamic distortion to leading order in slow roll

    astro-ph.CO 2026-07 conditional novelty 6.0 of 10

    Nondynamic distortion integrated out of a 13-parameter metric-affine action sources the entire inflaton kinetic term; monomial models depend only on exponent ratio while α-attractors recover modified Starobinsky observables.

  2. Inflation with the Gauss-Bonnet term in the Palatini formulation

    astro-ph.CO 2026-03 accept novelty 5.0 of 10

    In Palatini gravity the inflaton–Gauss–Bonnet coupling yields a negative Chern–Simons-like kinetic correction and similar GW modifications, with metric-like behaviour unless the kinetic term nearly flips sign.
