摘要：
The present work reports study on the interacting Ricci dark energy in a modified gravity theory named f(R, T) gravity. In the specific model f(R, T) = mu R + nu T we have observed a quintom-like behavior of the equation of state parameter and a transition from matter dominated to dark energy density has been observed through fraction density evolution. The statefinder parameters reveal that the model interpolates between dust and ACDM phases of the universe.
