N2 - The modified geodetic brane cosmology (MGBC) is tested with observational data. The MGBC is derived from the geodetic brane gravity action corrected by the extrinsic curvature of the braneworld. The density parameter coming from this additional term produces an accelerated expansion of geometrical origin. Subject to the supernovae Ia, observable Hubble parameter, baryon acoustic oscillations and cosmic microwave background probes, the obtained fit provides enough evidence in the sense that the extrinsic curvature effect is able to reproduce the accelerated expansion of the universe without the need for invoking dark energy, exotic matter or a cosmological constant. Moreover, the MGBC is free of the problems present in other braneworld models.
