Mirror dark matter structure formation

Mirror matter is a dark matter candidate whose gauge symmetry is identical to the Standard Model's SU(3)xSU(2)xU(1). If the discrete symmetry between the mirror sector (MS) and visible matter is unbroken, the chemical and nuclear processes of each sector have the same rates, making the model fully predictive. I will present the results of my structure formation simulation in the MS and the constraints that ensue on the mirror matter abundance and temperature. If time permits, I will also discuss how these parameters can differ from the ordinary sector in the early universe.
