Two-loop renormalisation and Higgs phenomenology in the five-dimensional MSSM
Ammar Abdalgabar, Alan S. Cornell, Aldo Deandrea +2
The five-dimensional Minimal Supersymmetric Standard Model (5D MSSM) provides an attractive framework in which power-law renormalisation group evolution naturally generates a sizea…
Composite Hybrid Inflation : Primordial Black Holes and Stochastic Gravitational Waves
Giacomo Cacciapaglia, Dhong Yeon Cheong, Aldo Deandrea +4
We investigate the production of primordial black holes and gravitational waves in composite hybrid inflation. Starting from an effective chiral Lagrangian with a dilaton and pions…
Gravitational waves from flavoured SU(2) early-universe phase transitions
Anna Chrysostomou, Alan S. Cornell, Luc Darmé +2
Flavourful extensions of the Standard Model aimed at explaining its fermionic mass structure typically rely on symmetries, broken at high-energy scales far beyond the reach of fore…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Quasinormal frequencies in Reissner-Nordström de Sitter black holes: constraints from space-time and scalar field parameters
Anna Chrysostomou, Alan S. Cornell, Aldo Deandrea +1
We examine the quasinormal modes exhibited by a massive scalar test field carrying an electric charge, oscillating in the outer region of a Reissner-Nordström de Sitter black hole…
A note on Strong Cosmic Censorship and its violation in Reissner-Nordström de Sitter black hole space-times
Anna Chrysostomou, Alan S. Cornell, Aldo Deandrea +1
Penrose's Strong Cosmic Censorship conjecture safeguards determinism in General Relativity. Within the initial value approach to General Relativity, proof of Strong Cosmic Censorsh…
