Classes of complete dark photon models constrained by Z-Physics

Miguel P. Bento, Howard E. Haber, João P. Silva

Dark Matter models that employ a vector portal to a dark sector are usually treated as an effective theory that incorporates kinetic mixing of the photon with a new U(1) gauge boso…

Kinetic recoupling of dark matter

Benjamin V. Lehmann, Logan Morrison, Stefano Profumo +1

We study the possibility that dark matter re-enters kinetic equilibrium with a radiation bath after kinetic decoupling, a scenario we dub kinetic recoupling. This naturally occurs,…

Tree-level Unitarity in SU(2)U(1)U(1) Models

Miguel P. Bento, Howard E. Haber, João P. Silva

In models with a U(1) gauge extension beyond the Standard Model, one can derive sum rules for the couplings of the theory that are a consequence of tree-level unitarity. In this pa…

Statement from the American Linear Collider Committee to the P5 subpanel

J. A. Bagger, S. Belomestnykh, P. C. Bhat +15

This statement from the American Linear Collider Committee to the P5 subpanel has three purposes. It presents a brief summary of the case for an Higgs factory that has eme…

Updated Constraints on Primordial Black Hole Evaporation

Mrunal Korwar, Stefano Profumo

The Hawking evaporation process, leading to the production of detectable particle species, constrains the abundance of light black holes, presumably of primordial origin. Here, we…

UV physics from IR features: new prospects from top flavor violation

Wolfgang Altmannshofer, Stefania Gori, Benjamin V. Lehmann +1

New physics in the rare top decays is currently very weakly constrained. We show that in a large class of Standard Model extensions, existing experimental co…
