Towards a viable scalar interpretation of
Sean Fraser, Carlo Marzo, Luca Marzola +2
Recent measurements of semileptonic B-meson decays seemingly imply violations of lepton flavor universality beyond the Standard Model predictions. With three-level explanations bas…
The EDGES 21 cm Anomaly and Properties of Dark Matter
Sean Fraser, Andi Hektor, Gert Hütsi +8
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at , if cosmological, requires the existence of new physics. The possible…
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…
Minimal flavor-changing models and muon after the measurement
Stefano Di Chiara, Andrew Fowlie, Sean Fraser +4
There has been a steady interest in flavor anomalies and their global fits as ideal probes of new physics. If the anomalies are real, one promising explanation is a new gauge…
Evolving Planck Mass in Classically Scale-Invariant Theories
K. Kannike, M. Raidal, C. Spethmann +1
We consider classically scale-invariant theories with non-minimally coupled scalar fields, where the Planck mass and the hierarchy of physical scales are dynamically generated. The…
Simulations of Galaxy Cluster Collisions with a Dark Plasma Component
Christian Spethmann, Hardi Veermäe, Tiit Sepp +4
Dark plasma is an intriguing form of self-interacting dark matter with an effective fluid-like behavior, which is well motivated by various theoretical particle physics models. We…
