Lectures on Semiclassical Methods for Composite Operators
Francesco Sannino
These lecture notes are intended as a coherent introduction to conformal field theory in general, and composite operators in particular, through a semiclassical framework for compu…
Infinite Heat Order in 3+1 Dimensions
Borut Bajc, Giulia Muco, Francesco Sannino +1
We investigate whether spontaneous symmetry breaking can persist up to arbitrarily high temperature in ultraviolet-complete quantum field theories in four spacetime dimensions. We…
Strong CP and the QCD Axion: Lecture Notes via Effective Field Theory
Francesco Sannino
These lecture notes provide a self-contained, graduate-level introduction to the strong problem and QCD axion physics from an effective field theory (EFT) viewpoint. We review…
Two-index SU(N) theories: QCD, Orientifolds, Super Yang-Mills, Lattice and Steven Weinberg's scattering legacy
Francesco Sannino
I review and improve on how two-index SU(N) gauge-fermion theories help access salient information about the large vacuum and spectrum of QCD, super Yang Mills and meson-meson…
