The generic basis and flavour non-universal SMEFT
Alakabha Datta, Jean-François Fortin, Jacky Kumar +3
Whenever an anomaly in the flavour sector appears, analyses are performed examining whether it can be explained by adding a small number of carefully-chosen flavour non-universal f…
Polarization Formalism for ALP-induced X-ray Emission from Magnetars
Jean-François Fortin, Kuver Sinha
Missions like NASA's Imaging X-ray Polarimetry Explorer (IXPE) are poised to provide an unprecedented view of the Universe in polarized X-rays. Polarization probes physical anisotr…
Conformal Blocks in Three Dimensions
Jean-François Fortin, Jingping Li, Alex Sandomirsky +1
We derive expressions for conformal blocks involving operators with arbitrary spins in 3-dimensional CFTs. We use previous results on the action of the OPE in the embedding space t…
Vacuum Decay Actions from Tunneling Potentials for General Spacetime Dimension
J. R. Espinosa, J. -F. Fortin
The tunneling potential method to calculate the action for vacuum decay is an alternative to the Euclidean bounce method that has a number of attractive features. In this paper we…
Magnetar Hard X-Ray Emission from Axion-like Particle Conversion
Jean-François Fortin, Marianne Gratton
We explore the possibility that axion-like-particles (ALPs), which would be produced in the core of magnetars and would then convert in the magnetosphere into photons, can explain…
Feynman Rules for Scalar Conformal Blocks
Jean-François Fortin, Sarah Hoback, Wen-Jie Ma +2
We complete the proof of "Feynman rules" for constructing -point conformal blocks with external and internal scalars in any topology for arbitrary in any spacetime dimension…
