Gauge invariant quantum backreaction in U(1) axion inflation / Galanti, Davide Campanella (INFN, Pisa) ; Conzinu, Pietro (INFN, Pisa ; CERN) ; Marozzi, Giovanni (INFN, Pisa) ; Santos da Costa, Simony (INFN, Pisa ; Trento U. ; TIFPA-INFN, Trento)
We evaluate the quantum backreaction due to a gauge field coupled to a pseudo scalar field driving a slow-roll inflationary stage, the so-called axion inflation. [...]

2d QCD and Integrability, Part II: Generalized QCD / Ambrosino, Federico (DESY) ; Komatsu, Shota (CERN)
We extend our study of integrable structures in large $N_c$ QCD$_2$ to a broad class of theories called the generalized QCD, which are given by the Lagrangian $\mathcal{L}\propto {\rm tr}\,B\wedge F- {\rm tr}\,V(B)$ coupled to quarks in the fundamental representation. [...]
