KOFFEE: Kaon Observables at Future Fermilab Experimental Extensions
Cari Cesarotti, Samuel Homiller
The rare decays and are among the most precisely predicted flavor observables, enabling determinations of the CKM matrix and its CP-violating ph…
Testing Viability of Benchmark Dark Matter Models for the Galactic Center Excess
Yongao Hu, Cari Cesarotti, Tracy R. Slatyer
We examine the status of benchmark simplified dark matter models that have been proposed to explain the GeV gamma-ray Galactic Center excess. We constrain the available parameter s…
Discovery Prospects for a Minimal Dark Matter Model at Cosmic and Intensity Frontier Experiments
Ahmed Alenezi, Cari Cesarotti, Stefania Gori +1
We explore the detection prospects for a minimal secluded dark matter model, where a fermionic dark matter particle interacts with the Standard Model (SM) via a kinetically mixed d…
A Field Guide to Event-Shape Observables Using Optimal Transport
Cari Cesarotti, Matt LeBlanc
We lay out the phenomenological behavior of event-shape observables evaluated by solving optimal transport problems between collider events and reference geometries -- which we nam…
Hitting the Thermal Target for Leptophilic Dark Matter
Cari Cesarotti, Gordan Krnjaic
We study future lepton collider prospects for testing predictive models of leptophilic dark matter candidates with a thermal origin. We calculate experimental milestones for testin…
New Forces From Sources
Cari Cesarotti, Yonatan Kahn, Gordan Krnjaic +2
Accelerator-based experiments reliant on charged pion and kaon decays to produce muon-neutrino beams also deliver an associated powerful flux of muons. Therefore, these experiments…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Oblique Lessons from the Mass Measurement at CDF II
Pouya Asadi, Cari Cesarotti, Katherine Fraser +2
The CDF collaboration recently reported a new precise measurement of the boson mass with a central value significantly larger than the SM prediction. We explore the effec…
Theory, phenomenology, and experimental avenues for dark showers: a Snowmass 2021 report
Guillaume Albouy, Jared Barron, Hugues Beauchesne +51
In this work, we consider the case of a strongly coupled dark/hidden sector, which extends the Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions…
The physics case of a 3 TeV muon collider stage
Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla +131
In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon coll…
Muon Collider Physics Summary
Chiara Aimè, Aram Apyan, Mohammed Attia Mahmoud +122
The perspective of designing muon colliders with high energy and luminosity, which is being investigated by the International Muon Collider Collaboration, has triggered a growing i…
Probing New Gauge Forces with a High-Energy Muon Beam Dump
Cari Cesarotti, Samuel Homiller, Rashmish K. Mishra +1
We propose a new beam dump experiment at a future TeV-scale muon collider. A beam dump would be an economical and effective way to increase the discovery potential of the collider…
Searching for Leptoquarks at Future Muon Colliders
Pouya Asadi, Rodolfo Capdevilla, Cari Cesarotti +1
A high energy muon collider can provide new and complementary discovery potential to the LHC or future hadron colliders. Leptoquarks are a motivated class of exotic new physics mod…

The Efficacy of Event Isotropy as an Event Shape Observable
Cari Cesarotti, Matthew Reece, Matthew J. Strassler
Event isotropy , an event shape observable that measures the distance of a final state from a spherically symmetric state, is designed for new physics signa…
Spheres To Jets: Tuning Event Shapes with 5d Simplified Models
Cari Cesarotti, Matthew Reece, Matthew J. Strassler
Hidden sectors could give rise to a wide variety of events at the LHC. Confining hidden sectors are known to engender events with a small number of jets when they are weakly-couple…
A Robust Measure of Event Isotropy at Colliders
Cari Cesarotti, Jesse Thaler
We introduce a new event shape observable -- event isotropy -- that quantifies how close the radiation pattern of a collider event is to a uniform distribution. This observable is…
