Upper Bound on the Cosmic Baryon Chemical Potential from Lepton-Flavor Asymmetry
Francesco Di Clemente, Alessandro Drago, Lorenzo Formaggio +3
We study the early Universe trajectory around the QCD transition in lepton-flavor-asymmetric cases with small total lepton asymmetry (), while allowing larg…

Cosmic Trajectories calculation with state of the art lattice QCD equation of state
Lorenzo Formaggio, Francesco Di Clemente, Geetika Yadav +2
We compute the full cosmic trajectories of the early Universe across the QCD phase diagram as the plasma cools from MeV to MeV, assuming -equilibrated matte…

Strange quark matter as dark matter: 40 years later, a reappraisal
Francesco Di Clemente, Marco Casolino, Alessandro Drago +2
Forty years ago Witten suggested that dark matter could be composed of macroscopic clusters of strange quark matter. This idea was very popular for several years, but it dropped ou…
