Phantom fluid cosmology: Impact of a phantom hidden sector on cosmological observables

James M. Cline, Matteo Puel, Takashi Toma +1

Phantom scalar theories are widely considered in cosmology, but rarely at the quantum level, where they give rise to negative-energy ghost particles. These cause decay of the vacuu…

Boosted dark matter from a phantom fluid

James M. Cline, Matteo Puel, Takashi Toma

It is known that theories of phantom dark energy, considered as quantum fields, predict a continuous production of positive- plus negative-energy particles, from spontaneous decay…

The Flavor of QCD Axion Dark Matter

Gonzalo Alonso-Álvarez, James M. Cline, Tianzhuo Xiao

We argue that demanding a consistent cosmological history, including the absence of domain walls and strongly interacting relics at the Peccei-Quinn scale, singles out two concrete…

Distortion of neutrino oscillations by dark photon dark matter

Gonzalo Alonso-Álvarez, Katarina Bleau, James M. Cline

A weakly coupled and light dark photon coupling to lepton charges is an intriguing dark matter candidate whose coherent oscillations alter the dispersion relations of lep…

NGC 1068 constraints on neutrino-dark matter scattering

James M. Cline, Matteo Puel

The IceCube collaboration has observed the first steady-state point source of high-energy neutrinos, coming from the active galaxy NGC 1068. If neutrinos interacted strongly enough…

PeV-scale leptogenesis, gravity waves and black holes from a SUSY-breaking phase transition

James M. Cline, Benoit Laurent, Stuart Raby +1

Supersymmetry is a highly motivated theoretical framework, whose scale of breaking may be at PeV energies, to explain null searches at the Large Hadron Collider. SUSY breaking thro…
