US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Invisible and displaced dark matter signatures at Belle II
Michael Duerr, Torben Ferber, Christopher Hearty +3
Many dark matter models generically predict invisible and displaced signatures at Belle II, but even striking events may be missed by the currently implemented search programme bec…
Searches for dark photons at accelerators
Matt Graham, Christopher Hearty, Mike Williams
Dark matter particles may interact with other dark matter particles via a new force mediated by a dark photon, , which would be the dark-sector analog to the ordinary p…
Forecasting dark showers at Belle II
Elias Bernreuther, Kai Böse, Torben Ferber +4
Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures at colliders. In this work, we study the sensitivity of…
Long-lived Dark Higgs and Inelastic Dark Matter at Belle II
Michael Duerr, Torben Ferber, Camilo Garcia-Cely +2
Inelastic dark matter is an interesting scenario for light thermal dark matter which is fully consistent with all cosmological probes as well as direct and indirect dark matter det…
Physics reach of a long-lived particle detector at Belle II
Sascha Dreyer, Torben Ferber, Anastasiia Filimonova +9
We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the \superkekb accelerator in Tsukuba, Japan. The new dete…
Improved Particle Identification Using Cluster Counting in a Full-Length Drift Chamber Prototype
Jean-François Caron, Christopher Hearty, Philip Lu +11
Single-cell prototype drift chambers were built at TRIUMF and tested with a $\sim\unit[210]{MeV/c}$ beam of positrons, muons, and pions. A cluster-counting technique is implemented…
Dark Sectors 2016 Workshop: Community Report
Jim Alexander, Marco Battaglieri, Bertrand Echenard +201
This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the…
Exploring Dark Sector Portals with High Intensity Experiments
Brian Batell, Nikita Blinov, Christopher Hearty +1
A broad program of searches at high intensity experiments during the coming decade and beyond will sensitively probe new light mediator particles interacting through the minimal re…
Dark Sector Physics at High-Intensity Experiments
Stefania Gori, Mike Williams, Phil Ilten +10
Is Dark Matter part of a Dark Sector? The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter…
Revised constraints and Belle II sensitivity for visible and invisible axion-like particles
Matthew J. Dolan, Torben Ferber, Christopher Hearty +2
Light pseudoscalars interacting pre-dominantly with Standard Model gauge bosons (so-called axion-like particles or ALPs) occur frequently in extensions of the Standard Model. In th…
