BPS-like potential for compactifications of heterotic M-theory?

Autor: Held, Johannes

Publikováno v: JHEP 1110:136, 2011

We analyze the possibility to rewrite the action of Horava-Witten theory in a BPS-like form, which means that it is given as a sum of squares of the supersymmetry conditions. To this end we compactify the theory on a seven dimensional manifold of SU(

DWSB for heterotic flux compactifications

Autor: Held, Johannes

Publikováno v: Fortschr. Phys. 59, No. 7-8, 711-715 (2011)

We investigate the construction of non-supersymmetric vacua in compactifications of heterotic string theory with intrinsic torsion and background fluxes. We do this by using the technique of domain-wall supersymmetry breaking (DWSB) that was develope

DWSB in heterotic flux compactifications

Autor: Held, Johannes, Lust, Dieter, Marchesano, Fernando, Martucci, Luca

Publikováno v: JHEP 1006:090,2010

We address the construction of non-supersymmetric vacua in heterotic compactifications with intrinsic torsion and background fluxes. In particular, we implement the approach of domain-wall supersymmetry breaking (DWSB) previously developed in the con

Heterotic Z6-II MSSM Orbifolds in Blowup

Autor: Nibbelink, Stefan Groot, Held, Johannes, Ruehle, Fabian, Trapletti, Michele, Vaudrevange, Patrick K. S.

Publikováno v: JHEP 0903:005,2009

Heterotic orbifolds provide promising constructions of MSSM-like models in string theory. We investigate the connection of such orbifold models with smooth Calabi-Yau compactifications by examining resolutions of the T^6/Z6-II orbifold (which are far
