The Flavor of Non-Abelian Orbifolds
Miguel Hernandez-Segura, Xiang-Gan Liu, Ricardo Perez-Martinez +1
In string model building, flavor symmetries can arise from the geometric features of the compactification space. In the case of heterotic orbifold models, modular and traditional f…

Star formation at z0.9 from the OTELO survey: A comprehensive view combining deep optical spectroscopy and infrared data
Rocío Navarro Martínez, Miguel Cerviño, Ricardo Pérez-Martínez +14
We aim to quantify the star formation rate (SFR) from deep optical spectroscopic data and far-infrared (FIR) photometry from a sample of galaxies at from the OTELO surv…

The Non-SUSY Orbifolder: a tool to build promising non-supersymmetric string models
Enrique Escalante-Notario, Ricardo Perez-Martinez, Saul Ramos-Sanchez +1
We introduce the non-SUSY orbifolder, which is a program developed in C++ that computes the low-energy effective theory of non-supersymmetric heterotic orbifold compactifications.…
