Quadratic Rastall gravity: from low-mass HESS J1731−347 to high-mass PSR J0952−0607 pulsars
Abstract Similar to Rastall gravity we introduce matter-geometry nonminimal coupling which is proportional to the gradient of quadratic curvature invariants. Those are mimicking the conformal trace anomaly when backreaction of the quantum fields to a curved spacetime geometry is considered. We consi...
