Improved modeling of $\gamma\gamma$ processes in ultraperipheral collisions at hadron colliders / Crépet, Nicolas (Ecole Normale Supérieure, Paris) ; d'Enterria, David (CERN) ; Shao, Hua-Sheng (Paris, LPTHE)
The CERN LHC is not only the current energy-frontier collider for parton-parton collisions, but has proven a powerful photon collider providing photon-photon ($\gamma\gamma$) collisions at center-of-mass energies and luminosities never reached before. [...]

$R^2$--Inflation Derived from 4d Strings, the Role of the Dilaton, and Turning the Swampland into a Mirage / Antoniadis, Ignatios (Chulalongkorn U. ; Paris, LPTHE) ; Nanopoulos, Dimitri V. (Athens Academy ; Texas A-M ; Athens U. ; HARC, Woodlands ; CERN) ; Olive, Keith A. (Minnesota U.)
Based on a previously derived superstring model possessing a cosmological sector that mimics Starobinsky inflation, we analyze several questions addressed in the recent literature: the generation of an effective $R^2$-term, the stability of the sgoldstino , the modular symmetry of the inflaton potential and the large distance swampland conjecture.
