String scale interacting dark matter from
Andreas Mütter, Patrick K. S. Vaudrevange
We show that in a wide class of string derived models of particle physics, heavy string modes with masses around the GUT scale can serve as a viable dark matter candidate. These he…
Discrete remnants of orbifolding
Steffen Biermann, Andreas Mütter, Erik Parr +2
We revisit the residual symmetries that survive the orbifold projections, and find additional transformations that have been overlooked in the past. Some of these transformations a…
Tension Between a Vanishing Cosmological Constant and Non-Supersymmetric Heterotic Orbifolds
Stefan Groot Nibbelink, Orestis Loukas, Andreas Mütter +2
We investigate under which conditions the cosmological constant vanishes perturbatively at the one-loop level for heterotic strings on non-supersymmetric toroidal orbifolds. To obt…
