Other
Gieseke, S., Grellscheid, D., Hamilton, K., Ribon, A., Richardson, P., Seymour, M., …Webber, B. (2006). Herwig++ 2.0 beta release note

A new release of the Monte Carlo program Herwig++ (version 2.0) is now available. The main new feature is the extension of the program to include simple hadron-hadron processes including the initial-state parton shower.

Book
Hitchin, N., Segal, G., & Ward, R. (1999). Integrable systems: twistors, loop groups, and Riemann surfaces. Oxford University Press

This textbook is designed to give graduate students an understanding of integrable systems via the study of Riemann surfaces, loop groups, and twistors. The book has its origins in a series of lecture courses given by the authors, all of whom are int... Read More about Integrable systems: twistors, loop groups, and Riemann surfaces..

Supersphere non-linear sigma model on the lattice (2023)
Presentation / Conference Contribution
Costa, I., Forini, V., Hoare, B., Meier, T., Patella, A., & Weber, J. H. (2023). Supersphere non-linear sigma model on the lattice. . https://doi.org/10.22323/1.430.0367

Two-dimensional O(N) non-linear sigma models are exactly solvable theories and have many applications, from statistical mechanics to their use as QCD toy models. We consider a supersymmetric extension, the non-linear sigma model on the supersphere~SN... Read More about Supersphere non-linear sigma model on the lattice.

Topological terms in abelian lattice field theories (2020)
Presentation / Conference Contribution
Gattringer, C., Anosova, M., Göschl, D., Sulejmanpasic, T., & Törek, P. (2020). Topological terms in abelian lattice field theories. . https://doi.org/10.22323/1.363.0082

In this contribution we revisit the lattice discretization of the topological charge for abelian lattice field theories. The construction departs from an initially non-compact discretization of the gauge fields and after absorbing 2π shifts of the ga...

Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter (2022)
Presentation / Conference Contribution
Anosova, M., Gattringer, C., Iqbal, N., & Sulejmanpasic, T. (2022). Numerical simulation of self-dual U(1) lattice field theory with electric and magnetic matter. . https://doi.org/10.22323/1.396.0386

We study a recently proposed formulation of U(1) lattice field theory with electric and magnetic matter based on the Villain formulation. This discretization allows for a duality that gives rise to relations between weak and strong gauge coupling. Th...

MMHT Updates, LHC jets and α S (2018)
Presentation / Conference Contribution
Thorne, R., Harland-Lang, L., & Martin, A. (2018). MMHT Updates, LHC jets and α S. In XXVI International Workshop on Deep-Inelastic Scattering and Related Subjects (DIS2018) - WG1: Structure Functions and Parton Densities. https://doi.org/10.22323/1.316.0030

We summarise the effects of including jet data from the LHC in the MMHT PDF extraction. We also present the latest results on the preferred value of the strong coupling α S ( M 2 Z ) αS(MZ2) in a number of fit variations. The best current value with...

Higgs Cosmology and Dark Matter (2018)
Presentation / Conference Contribution
Moss, I., & Gregory, R. (2018). Higgs Cosmology and Dark Matter. In 2nd World Summit : Exploring the dark side of the Universe (EDSU2018) - dark matter. https://doi.org/10.22323/1.335.0010

Higgs vacuum stability has important consequences for cosmology. In particular, we argue that if the Higgs vacuum is metastable, then the dark matter cannot contain a single black hole of mass less than 1015g in our entire past light cone. In additio...

Leptogenesis via varying Weinberg operator (2018)
Presentation / Conference Contribution

The Weinberg operator is a well-known solution to explain light neutrino masses. This operator violates lepton number and can provide non-equilibrium dynamics in the early Universe due to the suppression of tiny neutrino masses. A lot of underlying s...

We review the description of three-dimensional gauge theories with N = 4 supersymmetry in the presence of an omega background as an N = 4 supersymmetric quantum mechanics. We will focus throughout on a simple abelian example. The Hilbert space of sup... Read More about Three-Dimensional N = 4 Gauge Theories in Omega Background.

The Fate of the Higgs Vacuum (2016)
Presentation / Conference Contribution
Gregory, R., & Moss, I. (2016). The Fate of the Higgs Vacuum. In 38th International Conference on High Energy Physics (ICHEP2016)

This talk reviews our recent work showing how tiny black holes can act as nucleation sites for the decay of the metastable Higgs vacuum [1, 2, 3, 4]. We start by discussing the formation of thin wall bubbles of true vacuum inside a false vacuum, and... Read More about The Fate of the Higgs Vacuum.

Leptonic flavour mixing influenced by flavon cross couplings (2017)
Presentation / Conference Contribution
Zhou, Y. (2017). Leptonic flavour mixing influenced by flavon cross couplings. . https://doi.org/10.1088/1742-6596/888/1/012197

We develop an economical approach to connect flavon cross couplings with flavour mixing. A non-zero reactor mixing angle and almost maximal CP violation arise from cross couplings between flavons in the charged lepton and neutrino sectors. Within thi...
