Impurities Near the Light Cone
Gabriel Cuomo, Simone Giombi, Luigi Tizzano
The lightlike Wilson line cusp underlies the Sudakov double logarithm and is a central ingredient in gauge-theory factorization. We ask what replaces this behavior for general conf…
Comments on Symmetry Operators, Asymptotic Charges and Soft Theorems
Luigi Tizzano
We study the relation between emergent 1-form symmetries and soft photon theorems in QED. We show that in the relevant massive and massless kinematic regimes, described respectivel…
U(1) Gauging, Continuous TQFTs, and Higher Symmetry Structures
Adrien Arbalestrier, Riccardo Argurio, Luigi Tizzano
Quantum field theories can exhibit various generalized symmetry structures, among which higher-group symmetries and non-invertible symmetry defects are particularly prominent. In t…
Symmetries, Universes and Phases of QCD with an Adjoint Dirac Fermion
Jeremias Aguilera Damia, Giovanni Galati, Luigi Tizzano
We study 2d QCD with an adjoint Dirac fermion. Assuming that the IR limit of the massless theory is captured by a WZW coset CFT, we show that this CFT can be decomposed int…
Comments on Global Symmetries and Anomalies of SCFTs
Pietro Benetti Genolini, Luigi Tizzano
We study various aspects of global symmetries in five-dimensional superconformal field theories. Whenever a supersymmetry-preserving relevant deformation is available, the infrared…
