Stability in Axion Inflation with Strong Backreaction from a Massive Vector Boson
Michael J. Baker, Joaquim Iguaz Juan, Lorenzo Sorbo
We study a modification of the model of axion inflation coupled to a gauge field where the vector field is massive. In the conventional scenario with a massless gauge field,…
Heavy Vector Triplets at a Muon Collider
Francesca Acanfora, Michael J. Baker, Timothy Martonhelyi +1
Heavy spin-one particles are well-motivated new physics candidates that can have their origin in weakly coupled extensions of the Standard Model gauge group or in strongly coupled…
Explaining the PeV Neutrino Fluxes at KM3NeT and IceCube with Quasi-Extremal Primordial Black Holes
Michael J. Baker, Joaquim Iguaz Juan, Aidan Symons +1
The KM3NeT experiment has recently observed a neutrino with an energy around 100PeV, and IceCube has detected five neutrinos with energies above 1PeV. While there are no known astr…
Probing Dark Sectors with Exploding Black Holes: Gamma Rays
Michael J. Baker, Joaquim Iguaz Juan, Aidan Symons +1
The Hawking radiation from the explosion of a black hole would provide definitive information on the particle spectrum of nature. Here we quantify the potential of current and futu…
Could We Observe an Exploding Black Hole in the Near Future?
Michael J. Baker, Joaquim Iguaz Juan, Aidan Symons +1
Observation of an exploding black hole would provide the first direct evidence of primordial black holes, the first direct evidence of Hawking radiation, and definitive information…
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…
