What is the source of the PTA GW signal?
John Ellis, Malcolm Fairbairn, Gabriele Franciolini +7
The most conservative interpretation of the nHz stochastic gravitational wave background (SGWB) discovered by NANOGrav and other Pulsar Timing Array (PTA) Collaborations is astroph…
Gravitational Waves from SMBH Binaries in Light of the NANOGrav 15-Year Data
John Ellis, Malcolm Fairbairn, Gert Hütsi +4
The NANOGrav Collaboration has recently announced evidence for nHz gravitational waves (GWs), in the form of a Hellings-Downs angular correlation in the common-spectrum process tha…
Dimension-8 SMEFT Analysis of Minimal Scalar Field Extensions of the Standard Model
John Ellis, Ken Mimasu, Francesca Zampedri
We analyze the constraints obtainable from present data using the Standard Model Effective Field Theory (SMEFT) on extensions of the Standard Model with additional electroweak sing…
Oscillation probabilities for a PT-symmetric non-Hermitian two-state system
Jean Alexandre, Madeleine Dale, John Ellis +2
There is growing interest in viable quantum theories with PT-symmetric non-Hermitian Hamiltonians, but a formulation of transition matrix elements consistent with positivity and pe…
Top, Higgs, Diboson and Electroweak Fit to the Standard Model Effective Field Theory
Maeve Madigan
The Standard Model Effective Field Theory (SMEFT) provides a powerful theoretical framework for searching for subtle deviations from the Standard Model. In this talk, we present th…
STE-QUEST -- Space Time Explorer and QUantum Equivalence principle Space Test: The 2022 medium-class mission concept
Naceur Gaaloul, Holger Ahlers, Leonardo Badurina +45
Space-borne quantum technologies, particularly those based on atom interferometry, are heralding a new era of strategic and robust space exploration. The unique conditions of space…
