Predicting the orbifold origin of the MSSM
Erik Parr, Patrick K. S. Vaudrevange, Martin Wimmer
MSSM-like string models from the compactification of the heterotic string on toroidal orbifolds (of the kind ) have distinct phenomenological properties, like the spectrum o…
Contrast data mining for the MSSM from strings
Erik Parr, Patrick K. S. Vaudrevange
We apply techniques from data mining to the heterotic orbifold landscape in order to identify new MSSM-like string models. To do so, so-called contrast patterns are uncovered that…
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…
Deep learning in the heterotic orbifold landscape
Andreas Mütter, Erik Parr, Patrick K. S. Vaudrevange
We use deep autoencoder neural networks to draw a chart of the heterotic -II orbifold landscape. Even though the autoencoder is trained without knowing the phenomenol…
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…
Twisted superspace: Non-renormalization and fermionic symmetries in certain (heterotic string inspired) non-supersymmetric field theories
Stefan Groot Nibbelink, Erik Parr
Inspired by the tachyon-free non-supersymmetric heterotic SO(16)xSO(16) string we consider a special class of non-supersymmetric field theories: Those that can be obtained from sup…
