Physical resurgent extrapolation

Chiral extrapolation and physical insights

It has recently been established that finite-range regularisation in chiral effective field theory enables the accurate extrapolation of modern lattice QCD results to the chiral regime. We review some of the highlights of extrapolations of quenched lattice QCD results, including spectroscopy and magnetic moments. The ∆ resonance displays peculiar chiral features in the quenched theory which can...

Moritz Kaposi--Resurgent Dermatologist.

M Kaposi (1837-1902) was born to Jewish family in Hungary, originally his surname was Cohen, but with his conversion to Catholic faith, he changed it to Kaposi in 1871, in reference to his town of birth. Kaposi studied at the University of Vienna, where he received his medical degree in 1861. Kaposi married Hebra’s daughter Martha Hebra. Together with his mentor Ferdinand Von Hebra he authored ...

Field-Theory Amplitudes as Resurgent Functions

A series of informal seminars at graduate-student level on the subject of coupling dependence in quantum field theory, with an elementary introduction to the notion of resurgent function that forms the appropriate framework for the coupling dependence of strictly renormalizable theories. While most of the discussion is pedagogical, there are also a few things for the expert: we demonstrate, by ...
