 On the Maximal Strength of a First-Order Electroweak Phase Transition and its Gravitational Wave Signal / Ellis, John ; Lewicki, Marek ; No, José Miguel What is the maximum possible strength of a first-order electroweak phase transition and the resulting gravitational wave (GW) signal? While naively one might expect that supercooling could increase the strength of the transition to very high values, for strong supercooling the Universe is no longer radiation-dominated and the vacuum energy of the unstable minimum of the potential dominates the expansion, which can jeopardize the successful completion of the phase transition.

 A fixed-target programme at the LHC for heavy-ion, hadron, spin and astroparticle physics: AFTER@LHC / Kikoła, D. (Warsaw U. of Tech.) ; Brodsky, S.J. (SLAC) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Da Silva, C. (Los Alamos) ; Donato, F. (Turin U. ; INFN, Turin) ; Echevarria, M.G. (INFN, Pavia) ; Ferreiro, E.G. (Santiago de Compostela U. ; Santiago de Compostela U., IGFAE ; Ecole Polytechnique) ; Hadjidakis, C. (Orsay, IPN) ; Hřivnáčová, I. (Orsay, IPN) ; Klein, A. (Los Alamos) et al. Thanks to its multi-TeV LHC proton and lead beams, the LHC complex allows one to perform the most energetic fixed-target experiments ever and to study with high precision pp, pd and pA collisions at sqrt(s_NN) = 115 GeV and Pbp and PbA collisions at sqrt(s_NN) = 72 GeV.
