Option Hedging with Risk Averse Reinforcement Learning
Edoardo Vittori, Michele Trapletti, Marcello Restelli
In this paper we show how risk-averse reinforcement learning can be used to hedge options. We apply a state-of-the-art risk-averse algorithm: Trust Region Volatility Optimization (…
Sparticle Spectrum of Large Volume Compactification
Kiwoon Choi, Hans Peter Nilles, Chang Sub Shin +1
We examine the large volume compactification of Type IIB string theory or its F theory limit and the associated supersymmetry breakdown and soft terms. It is crucial to incorporate…
Heterotic MSSM on a Resolved Orbifold
Michael Blaszczyk, Stefan Groot Nibbelink, Fabian Ruehle +2
We construct an MSSM with three generations from the heterotic string compactified on a smooth 6D internal manifold using Abelian gauge fluxes only. The compactification space is o…
A Z2xZ2 standard model
Michael Blaszczyk, Stefan Groot Nibbelink, Michael Ratz +3
We present a Z_2 x Z_2 orbifold compactification of the E_8 x E_8 heterotic string which gives rise to the exact chiral MSSM spectrum. The GUT breaking SU(5) to SU(3)_C x SU(2)_L x…
Heterotic Z6-II MSSM Orbifolds in Blowup
Stefan Groot Nibbelink, Johannes Held, Fabian Ruehle +2
Heterotic orbifolds provide promising constructions of MSSM-like models in string theory. We investigate the connection of such orbifold models with smooth Calabi-Yau compactificat…
Non-Abelian bundles on heterotic non-compact K3 orbifold blowups
Stefan Groot Nibbelink, Filipe Paccetti Correia, Michele Trapletti
Instantons on Eguchi-Hanson spaces provide explicit examples of stable bundles on non-compact four dimensional C^2/Z_n orbifold resolutions with non-Abelian structure groups. With…
