ADM, BMS, and some puzzling interconnections / Veneziano, Gabriele (CERN ; College de France)
The precise connection between the ADM and BMS formalisms is still far from being fully understood. It leads superficially to some puzzles whose resolution can provide new interesting physical insights. [...]

Spontaneous Magnetogenesis at the Electroweak Phase Transition / Domcke, Valerie (CERN) ; Ema, Yohei (CERN) ; Patel, Teerthal (Vanderbilt U.)
Spontaneous CP violation during the electroweak phase transition can induce a twisting of the magnetic field configuration of Standard Model dumbbells, resulting in sizable intergalactic magnetic fields and a small baryon asymmetry, in agreement with observations. [...]
