Split SIMPs with Decays
Andrey Katz, Ennio Salvioni, Bibhushan Shakya
We discuss a minimal realization of the strongly interacting massive particle (SIMP) framework. The model includes a dark copy of QCD with three colors and three light flavors. A m…
Looking for MACHOs in the Spectra of Fast Radio Bursts
Andrey Katz, Joachim Kopp, Sergey Sibiryakov +1
We explore a novel search strategy for dark matter in the form of massive compact halo objects (MACHOs) such as primordial black holes or dense mini-halos in the mass range from $1…
Dynamical Friction in Interacting Relativistic Systems
Andrey Katz, Aleksi Kurkela, Alexander Soloviev
We study dynamical friction in interacting relativistic systems with arbitrary mean free paths and medium constituent masses. Our novel framework recovers the known limits of ideal…
On Lepton Flavor Universality in Top Quark Decays
Jernej F. Kamenik, Andrey Katz, Daniel Stolarski
We propose a novel strategy to test lepton flavor universality (LFU) in top decays, applicable to top pair production at colliders. Our proposal exploits information in kinematic d…
Femtolensing by Dark Matter Revisited
Andrey Katz, Joachim Kopp, Sergey Sibiryakov +1
Femtolensing of gamma ray bursts (GRBs) has been put forward as an exciting possibility to probe exotic astrophysical objects with masses below solar masses such as smal…
Anomalous and Diboson Resonances at the LHC
Ahmed Ismail, Andrey Katz
We propose novel collider searches which can significantly improve the LHC reach to new gauge bosons with mixed anomalies with the electroweak (EW) gauge group. Such a ne…
