1-loop renormalisability of integrable sigma-models from 4d Chern-Simons theory

Sylvain Lacroix, Nat Levine, Anders Wallberg

Large families of integrable 2d sigma-models have been constructed at the classical level, partly motivated by the utility of integrability on the string worldsheet. It is natural to ask whether these theories are renormalisable at the quantum level, and whether they define quantum integrable field…

Vector Boson Fusion Signatures of Superheavy Majorana Neutrinos at Muon Colliders

Parham Dehghani, Mariana Frank, Benjamin Fuks

We investigate the sensitivity of future high-energy muon colliders to heavy Majorana neutrinos, considering both opposite-sign ($\mu^+\mu^-$) and same-sign ($\mu^+\mu^+$) collision modes. We focus on $\mu^+\mu^-$ colliders operating at centre-of-mass energies of 1, 3 and 10~TeV, as well as the…

Bispectrum from five-dimensional inflation

Ignatios Antoniadis, Auttakit Chatrabhuti, Jules Cunat, Hiroshi Isono

It was proposed that five-dimensional (5D) inflation can blow up the size of a compact dimension from the 5D Planck length to the micron size, as required by the dark dimension proposal, relating the weakness of the actual gravitational force to the size of the observable universe. Moreover, it was…

Möbius randomness in the Hartle-Hawking state

Victor Godet

We consider quantum cosmology for toroidal universes in d+1 dimensions. The Hilbert space is the space of square-integrable automorphic forms for GL(d). The Hartle-Hawking state is defined as a Poincaré sum over the no-boundary geometries. We obtain its representation in the Langlands spectral…
