Five-dimensional strange quark matter cosmological model with string cloud

The work in this paper is devoted to the study of Kaluza-Klein (KK) cosmological model with strange quark matter attached to string cloud in the framework of metric version of f(R) gravity. By utilizing hybrid expansion law for average scale factor of the model i.e. a(t) = e(alpha t)t(beta), here alpha and beta are positive constants, we derive the solution of the field equations of KK model in the f(R) gravity. Various dynamical parameters of the model are obtained and their behavior is analyzed through graphical representation. We observe that the analysis of deceleration parameter exhibits a smooth transition of the universe from early decelerated phase to current accelerated epoch. Also, we discussed well-known state-finder parameters {r,s} and {r,q} planes which are analyzed by graphical representation.
