It is shown that classical decay of unstable D-branes in bosonic and superstring theories produces pressureless gas with non-zero energy density. The energy density is stored in the open string fields, even though around the minimum of the tachyon potential there are no open string degrees of freedom. We also give a description of this phenomenon in an effective field theory.

  1. Quark flavors in hot and dense holographic QCD: setup and comparison to data

    hep-ph 2025-07 conditional novelty 7.0 of 10

    A 2+1 flavor holographic QCD model fitted to lattice thermodynamics predicts a smoother nuclear-to-quark matter transition with lower latent heat than earlier V-QCD models.
