Lower bound on the primordial black hole merger rate
Ville Vaskonen, Hardi Veermäe
We derive a lower bound on the merger rate of primordial black hole (PBH) binaries by estimating the maximal fraction of binaries that were perturbed between formation in the early…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Vacuum Stability and Perturbativity of SU(3) Scalars
Matti Heikinheimo, Kristjan Kannike, Florian Lyonnet +3
We calculate the vacuum stability conditions and renormalisation group equations for the extensions of standard model with a higher colour multiplet scalar up to the representation…
Collisionless shocks in self-interacting dark matter
Matti Heikinheimo, Martti Raidal, Christian Spethmann +1
Self-interacting dark matter has been proposed as a solution to small scale problems in cosmological structure formation, and hints of dark matter self scattering have been observe…
Implications of effective axial-vector coupling of gluon for spin polarizations at the LHC
E. Gabrielli, A. Racioppi, M. Raidal +1
We analyze the impact of effective axial-vector coupling of the gluon on spin polarization observables in pair production at the LHC. Working at leading order in QCD, we…
