Slow-roll trajectories in chromo-natural and gauge-flation models: An exhaustive analysis.

We present an exhaustive analysis on the background inflationary solutions of the chromo-natural model. We show that starting from an arbitrary axion field value 0∈(0,fπ), it is possible to have slow-roll inflation with enough number of e-folds and determine the allowed region of the parameters corresponding to each 0 value. Having the available parameter space, we then study the behavior of the solutions with respect to the initial value of the axion field. [ABSTRACT FROM AUTHOR]
