Data-Driven Predictions for Dark Photon and Millicharged Particle Production
Elizabeth Allison, Nikita Blinov
Accurate signal predictions are essential for interpreting and optimizing fixed-target searches for new physics. Even in minimal models such as the dark photon () or millicharg…

Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
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…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
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…
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…
A Snowmass Whitepaper: Dark Matter Production at Intensity-Frontier Experiments
G. Krnjaic, N. Toro, A. Berlin +11
Dark matter particles can be observably produced at intensity-frontier experiments, and opportunities in the next decade will explore important parameter space motivated by thermal…
Snowmass White Paper: Strong CP Beyond Axion Direct Detection
Nikita Blinov, Nathaniel Craig, Matthew J. Dolan +5
We sketch recent progress and promising future directions for research connected with the strong CP problem. Topics surveyed include axion dark matter substructure and its gravitat…
New Ideas in Baryogenesis: A Snowmass White Paper
Gilly Elor, Julia Harz, Seyda Ipek +21
The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of the Universe. This observation is a clear sign of new physics beyond the Standard Model. Ther…
Physics Opportunities for the Fermilab Booster Replacement
John Arrington, Joshua Barrow, Brian Batell +49
This white paper presents opportunities afforded by the Fermilab Booster Replacement and its various options. Its goal is to inform the design process of the Booster Replacement ab…
Neutrino Self-Interactions: A White Paper
Jeffrey M. Berryman, Nikita Blinov, Vedran Brdar +31
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known…
Synergy between cosmological and laboratory searches in neutrino physics
Martina Gerbino, Evan Grohs, Massimiliano Lattanzi +21
The intersection of the cosmic and neutrino frontiers is a rich field where much discovery space still remains. Neutrinos play a pivotal role in the hot big bang cosmology, influen…
Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements
Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
Towards a Realistic Model of Dark Atoms to Resolve the Hubble Tension
Nikita Blinov, Gordan Krnjaic, Shirley Weishi Li
It has recently been shown that a subdominant hidden sector of atomic dark matter in the early universe provides a novel avenue towards resolving the Hubble () tension while m…
Densities of States and the CKN Bound
Nikita Blinov, Patrick Draper
The holographic principle implies that quantum field theory overcounts the number of independent degrees of freedom in quantum gravity. An argument due to Cohen, Kaplan, and Nelson…
Multi-track Displaced Vertices at B-Factories
Mason Acevedo, Albany Blackburn, Nikita Blinov +2
We propose a program at B-factories of inclusive, multi-track displaced vertex searches, which are expected to be low background and give excellent sensitivity to non-minimal hidde…
Characterizing Dark Matter Signals with Missing Momentum Experiments
Nikita Blinov, Gordan Krnjaic, Douglas Tuckler
Fixed target missing-momentum experiments such as LDMX and M are powerful probes of light dark matter and other light, weakly coupled particles beyond the Standard Model (SM).…
Dark Matter Targets for Axion-like Particle Searches
Nikita Blinov, Matthew J. Dolan, Patrick Draper +1
Many existing and proposed experiments targeting QCD axion dark matter (DM) can also search for a broad class of axion-like particles (ALPs). We analyze the experimental sensitivit…
Dark Sector Equilibration During Nucleosynthesis
Asher Berlin, Nikita Blinov, Shirley Weishi Li
Light, weakly-coupled dark sectors may be naturally decoupled in the early universe and enter equilibrium with the Standard Model bath during the epoch of primordial nucleosynthesi…
A Thermal Neutrino Portal to Sub-MeV Dark Matter
Asher Berlin, Nikita Blinov
Thermal relics lighter than an MeV contribute to the energy density of the universe at the time of nucleosynthesis and recombination. Constraints on extra radiation degrees of free…
Consequences of Fine-Tuning for Fifth Force Searches
Nikita Blinov, Sebastian A. R. Ellis, Anson Hook
