How robust are gravitational wave predictions from cosmological phase transitions?
Peter Athron, Lachlan Morris, Zhongxiu Xu
Gravitational wave (GW) predictions of cosmological phase transitions are almost invariably evaluated at either the nucleation or percolation temperature. We investigate the effect…
Can supercooled phase transitions explain the gravitational wave background observed by pulsar timing arrays?
Peter Athron, Andrew Fowlie, Chih-Ting Lu +4
Several pulsar timing array collaborations recently reported evidence of a stochastic gravitational wave background (SGWB) at nHz frequencies. Whilst the SGWB could originate from…
Precise calculation of the W boson pole mass beyond the Standard Model with FlexibleSUSY
Peter Athron, Markus Bach, Douglas H. J. Jacob +3
We present an updated calculation of the W boson pole mass in models beyond the Standard Model with FlexibleSUSY. The calculation has a decoupling behaviour and allows for a precis…
Hadronic Uncertainties versus New Physics for the boson Mass and Muon Anomalies
Peter Athron, Andrew Fowlie, Chih-Ting Lu +3
There are now two single measurements of precision observables that have major anomalies in the Standard Model: the recent CDF measurement of the mass shows a deviation an…
Two-loop Prediction of the Anomalous Magnetic Moment of the Muon in the Two-Higgs Doublet Model with GM2Calc 2
Peter Athron, Csaba Balazs, Adriano Cherchiglia +4
We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment () in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is…
FlexibleDecay: An automated calculator of scalar decay widths
Peter Athron, Adam Büchner, Dylan Harries +3
We present FlexibleDecay, a tool to calculate decays of scalars in a broad class of BSM models. The tool aims for high precision particularly in the case of Higgs boson decays. In…
New physics explanations of in light of the FNAL muon measurement
Peter Athron, Csaba Balázs, Douglas HJ Jacob +3
The Fermilab Muon experiment recently reported its first measurement of the anomalous magnetic moment , which is in full agreement with the previous BNL…
Z' mass limits and the naturalness of supersymmetry
P. Athron, D. Harries, A. G. Williams
The discovery of a 125 GeV Higgs boson and rising lower bounds on the masses of superpartners have lead to concerns that supersymmetric models are now fine tuned. Large stop masses…
