The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Deep observations of the Type IIB flux landscape
Aman Chauhan, Michele Cicoli, Sven Krippendorf +3
We present deep observations in targeted regions of the string landscape through a combination of analytic and dedicated numerical methods. Specifically, we devise an algorithm des…
Cambridge Lectures on The Standard Model
Fernando Quevedo, Andreas Schachner
These lecture notes cover the Standard Model (SM) course for Part III of the Cambridge Mathematical Tripos, taught during the years 2020-2023. The course comprised 25 lectures and…
New non-supersymmetric flux vacua in string theory
Sven Krippendorf, Andreas Schachner
In this note we construct large ensembles of supersymmetry breaking solutions arising in the context of flux compactifications of type IIB string theory. This class of solutions wa…
W0_sample = np.random.normal(0,1)?
Julian Ebelt, Sven Krippendorf, Andreas Schachner
In this note we explore the distribution of vacuum expectation values of the superpotential in explicit Type IIB flux compactifications. We show that the distribution can be…
JAXVacua -- A Framework for Sampling String Vacua
Abhishek Dubey, Sven Krippendorf, Andreas Schachner
Moduli stabilisation in string compactifications with many light scalars remains a major blind-spot in the string landscape. In these regimes, analytic methods cease to work for ge…
Testing BSM Physics with Gravitational Waves
Francesco Muia, Fernando Quevedo, Andreas Schachner +1
The Cosmic Gravitational Wave Background (CGWB) is an irreducible background of gravitational waves generated by particle exchange in the early Universe plasma. Standard Model part…
Type IIB at eight derivatives: insights from Superstrings, Superfields and Superparticles
James T. Liu, Ruben Minasian, Raffaele Savelli +1
We study the non-linear structure of Type IIB eight-derivative couplings involving the metric and the complexified three-form . We show that, at the level of five-point string…
A Database of Calabi-Yau Orientifolds and the Size of D3-Tadpoles
Chiara Crinò, Fernando Quevedo, Andreas Schachner +1
The classification of 4D reflexive polytopes by Kreuzer and Skarke allows for a systematic construction of Calabi-Yau hypersurfaces as fine, regular, star triangulations (FRSTs). U…
Probing the Structure of String Theory Vacua with Genetic Algorithms and Reinforcement Learning
Alex Cole, Sven Krippendorf, Andreas Schachner +1
Identifying string theory vacua with desired physical properties at low energies requires searching through high-dimensional solution spaces - collectively referred to as the strin…
Systematics of type IIB moduli stabilisation with odd axions
Michele Cicoli, Andreas Schachner, Pramod Shukla
Moduli stabilisation in superstring compactifications on Calabi-Yau orientifolds remains a key challenge in the search for realistic string vacua. In particular, odd moduli arising…
Systematics of the Expansion in F-Theory
Michele Cicoli, Fernando Quevedo, Raffaele Savelli +2
Extracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field th…
Searching the Landscape of Flux Vacua with Genetic Algorithms
Alex Cole, Andreas Schachner, Gary Shiu
In this paper, we employ genetic algorithms to explore the landscape of type IIB flux vacua. We show that genetic algorithms can efficiently scan the landscape for viable solutions…
Large Field Ranges from Aligned and Misaligned Winding
Arthur Hebecker, Daniel Junghans, Andreas Schachner
We search for effective axions with super-Planckian decay constants in type IIB string models. We argue that such axions can be realised as long winding trajectories in complex-str…
Universal scaling of unequal-time correlation functions in ultracold Bose gases far from equilibrium
A. Schachner, A. Piñeiro Orioli, J. Berges
We explore the far-from-equilibrium dynamics of Bose gases in a universal regime associated to nonthermal fixed points. While previous investigations concentrated on scaling functi…
