$R^2$--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.

How large could CP violation in neutral $B$ meson mixing be? Implications for baryogenesis and upcoming searches / Miró, Carlos (Valencia U.) ; Escudero, Miguel (CERN) ; Nebot, Miguel (Valencia U.)
CP violation in neutral $B$ meson oscillations is an experimental observable that could be directly related to the baryon asymmetry of the Universe through the $B$-Mesogenesis mechanism. [...]

Assessing the Impact of Unequal Noises and Foreground Modeling on SGWB Reconstruction with LISA / Kume, Jun'ya ; Peloso, Marco (Padua U. ; INFN, Padua) ; Pieroni, Mauro (CERN) ; Ricciardone, Angelo (Pisa U. ; INFN, Pisa)
In the search for stochastic gravitational wave backgrounds (SGWB) of cosmological origin with LISA, it is crucial to account for realistic complications in the noise and astrophysical foreground modeling that may impact the signal reconstruction. [...]
