Axinos in Cosmology and at Colliders
Ayres Freitas, Frank Daniel Steffen, Nurhana Tajuddin +1
The axino, the fermionic superpartner of the axion, is a well-motivated candidate for cold dark matter if it is the lightest supersymmetric particle. Since the axino couples very w…
Late Energy Injection and Cosmological Constraints in Axino Dark Matter Scenarios
Ayres Freitas, Frank Daniel Steffen, Nurhana Tajuddin +1
Taking into account effects of late energy injection, we examine big bang nucleosynthesis (BBN) constraints on axino dark matter scenarios with long-lived charged sleptons. We calc…
Upper Limits on the Peccei-Quinn Scale and on the Reheating Temperature in Axino Dark Matter Scenarios
Ayres Freitas, Frank Daniel Steffen, Nurhana Tajuddin +1
Considering axino cold dark matter scenarios with a long-lived charged slepton, we study constraints on the Peccei-Quinn scale f_a and on the reheating temperature T_R imposed by t…
