Searching for Quirks at LHCb
Xabier Cid Vidal, Miguel Fernández Gómez, Matthew Low +3
Quirks are heavy particles connected by a flux tube from a hidden confining force that remain weakly constrained in large regions of their parameter space. This flux tube acts as a…
Directly Probing Neutrino Interactions through CMB Phase Shift Measurements
Gabriele Montefalcone, Subhajit Ghosh, Kimberly K. Boddy +2
Perturbations in the cosmic neutrino background produce a characteristic phase shift in the acoustic oscillations imprinted in the anisotropies of the cosmic microwave background (…
Echoes of Self-Interacting Dark Matter from Binary Black Hole Mergers
Amitayus Banik, Jeong Han Kim, Jun Seung Pi +1
Dark matter (DM) environments around black holes (BHs) can influence their mergers through dynamical friction, causing gravitational wave (GW) dephasing during the inspiral phase.…
Boiling After the Dust Settles: Constraining First-Order Phase Transitions During Dark Energy Domination
Seth Koren, Yuhsin Tsai, Runqing Wang
A first-order phase transition could occur in the late universe when vacuum energy begins dominating the energy density () and convert some latent heat into other f…
Dark Matter-Radiation Scattering Enhances CMB Phase Shift through Dark Matter-loading
Subhajit Ghosh, Daven Wei Ren Ho, Yuhsin Tsai
A phase shift in the acoustic oscillations of CMB spectra is a characteristic signature for the presence of non-photon radiation propagating differently from photons, even when the…
