Electroweak stars: how nature may capitalize on the standard model's ultimate fuel
De-Chang Dai, Arthur Lue, Glenn Starkman +1
We study the possible existence of an electroweak star - a compact stellar-mass object whose central core temperature is higher than the electroweak symmetry restoration temperatur…
Unparticle dark energy
De-Chang Dai, Sourish Dutta, Dejan Stojkovic
We examine a dark energy model where a scalar unparticle degree of freedom plays the role of quintessence. In particular, we study a model where the unparticle degree of freedom ha…
Constraints on dark matter particles charged under a hidden gauge group from primordial black holes
De-Chang Dai, Katherine Freese, Dejan Stojkovic
In order to accommodate increasingly tighter observational constraints on dark matter, several models have been proposed recently in which dark matter particles are charged under s…
Manual of BlackMax, a black-hole event generator with rotation, recoil, split branes, and brane tension
De-Chang Dai, Cigdem Issever, Eram Rizvi +3
This is the users manual of the black-hole event generator BlackMax, which simulates the experimental signatures of microscopic and Planckian black-hole production and evolution at…
Neutralino dark matter stars can not exist
De-Chang Dai, Dejan Stojkovic
Motivated by the recent "Cosmos Project" observation of dark-matter concentrations with no ordinary matter in the same place, we study the question of the existence of compact obje…
