Impact of Supercooling on Direct Searches for Dark Matter and Gravitational Wave Backgrounds
Speaker: Alfredo Stanzione (La Sapienza Univ., Roma) An interesting feature of a cosmological phase transition can be a stage of exponential expansion (supercooling). The modified expansion history and the entropy injection at reheating, can affect the final energy fraction of dark matter. In this paper, we revisit the calculation of the freeze-out and freeze-in dynamics, …

The KOTO II experiment at J-PARC
Speaker: Cristina Lazzeroni (University of Birmingham) The main aim of the proposed KOTO II experiment at JPARC is the measurement of the ultra-rare decay KL to pi0 nu nu. This decay is heavily suppressed and its branching is very well predicted by the SM (3x 10-11 with about 2% uncertainty), thereby exhibiting an exceptional sensitivity …
