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…
